Chuck Lorre Productions

Background
This is the vanity card of Chuck Lorre (best known for his work on Dharma & Greg, Two and a Half Men, The Big Bang Theory, Mike & Molly and Mom), founded in the 1990s, but incorporated on January 10, 2000 in Los Angeles, California.

1st Logo (January 2-December 17, 1995, November 10, 2011)
Logo: We see an Apple Macintosh SE (specifically the less-common dual disk model) on a desk with lots of office supplies surrounding it, including a keyboard, mouse, pencils and a floppy disk, as well as a drink. "Chuck Lorre Productions" in white Peignot font (the font used on the Viacom "Pinball", as well as the title card of The Mary Tyler Moore Show and the first logo of The Jerry Springer Show), is written on the monitor against a dark blue background.

Variants:
 * The Macintosh SE (1987) is replaced with a later Compact Macintosh, either a Macintosh Classic (1990) or Classic II (1992), but it cannot be determined exactly which because both use the same case, and the name was removed from the computer in the logo. The camera angle is also different.
 * The font is changed from Peignot to a standard sans-serif font (i.e. Arial). This version also has a decanter on the desk.

FX/SFX: None.

Music/Sounds: The closing theme of Cybill or a CBS generic theme on original airings.

Availability: Originally seen on season 1 and early season 2 episodes of Cybill when originally aired on CBS. It later reappeared in the Big Bang Theory episode "The Ornithophobia Diffusion".

Legacy: Not as well known as the card below (see the 3rd logo).

2nd Logo (March 13, 1995)
Logo: We see a photograph of a man holding a bag of cheese puffs and waving his hand. The text "Chuck Lorre Productions" is seen at the bottom.

FX/SFX: The film scratches moving.

Music/Sounds: The closing theme.

Availability: Rare. Seen only on the Cybill episode "The Replacements".

3rd Logo (September 24, 1997-)
Nickname: "The Essays"

Logo: On a white background, we see "CHUCK LORRE PRODUCTIONS" at the top of the screen in a black typewriter font, with a number next to it that groups how many of the logos there have been. Below it is a short, humorous (and often cynical and at times, political) essay in a very small font which must be paused to read it.

Trivia:
 * The logo was briefly retired due to the media taking the essays too seriously during the Charlie Sheen controversy that went on season 8 of Two and a Half Men.
 * There are currently more than 700 different essays.
 * This logo was parodied in MAD magazine when it spoofed The Big Bang Theory.
 * A special coffee-table book was printed in 2012 called What Doesn't Kill Us Makes Us Bitter, which features artsy arrangements of hundreds of Chuck's essays.
 * This logo has been used as vanity cards with tags of numbers since September 1997.

Variants:
 * When this logo first appeared, it featured a black background with white text. Starting on September 28, 1999, it was later inverted so it could be easier to read, especially after VHS got retired.
 * On some occassions, photos, symbols and drawings replace the normal text. The card may also look different, too.
 * In some cases, a card numbered "111" is used when Lorre has "nothing to write about". It has only been seen on two occasions.
 * On the season 7 episode of Two and a Half Men, "Warning, It's Dirty", "CHUCK LORRE" is replaced with another logo called "A Marty Pepper Production" in an old-school Broadway background with a funny voice saying "It's a Pepper!", followed by a cuckoo sound. The vanity card number for this one is #271. However, a different version of this variant with the company name can be seen at Lorre's website.
 * Special "Censored" cards have been used when the networks reject a certain essay.
 * Essay #570 features an Apple Animoji pig who says "Believe me!".
 * On the Big Bang Theory episode "The Ornithophobia Diffusion", the essay is replaced with an image of the 1st logo (the later Peignot variant) and what Chuck Lorre remembers his first vanity card when he was working on Grace Under Fire and Cybill. The number for this one is #366.

FX/SFX: None.

Music/Sounds: A brief sound clip of a heavenly choir singing, none, or the closing theme of the series. ABC and CBS airings used their generic themes.

Music/Sounds Variants:
 * On the Two and a Half Men series finale "Of Course He's Dead", the choir is rearranged.
 * On the Big Bang Theory episode "The Bon Voyage Reaction", Rajesh Koothrappali (played by Kunal Nayyar) is still talking about Lucy throughout the show's closing theme before his jabbering (including he says "So, you know a silver lining...") is cut off by the 2003 Warner Bros. Television logo's music.

Availability: Common. Seen on shows such as Dharma & Greg, Two and a Half Men, Mike & Molly, The Big Bang Theory, Mom, Young Sheldon, The Kominsky Method, B Positive, and Bob Hearts Abishola.

Legacy: Overall, thanks to its unique concept and funny essays, it's a very popular logo and is well-liked by many.

Archives: There is a complete collection (which is updated every time a new episode airs) of the vanity cards at Chuck Lorre's website.

4th Logo (August 25, 2017-January 12, 2018)
Logo: On a black background, we see a white shield also resembling that of a coat-of-arms. Surrounding it is some Lorem Ipsum-like text (which has four words that read "HUMILITAS FICTA", "UN-FOCUSED RAGE", "NEUROTIC ANXIETY" and "SELF-OBSESSION") with a crown and the stacked words "Chuck Lorre Productions" in a medieval font inside.

Trivia: There are two parts of the shield that represent Chuck Lorre's two long-running CBS sitcoms: an atom represents The Big Bang Theory, and a symbol of two men and a kid represents Two and a Half Men.

FX/SFX: None.

Music/Sounds: The end theme of the show or none.

Availability: Seen only on Disjointed.
