Giggling Goose Productions

Background
Giggling Goose Productions was founded in 1988 by television writer/producer Gary Gilbert. The company focused on producing pilots, the best known of which was The Seinfeld Chronicles which was picked up as Seinfeld.

(July 21, 1988-December 17, 1989)
Logo: On a blue/black gradient background, we see the silver text:

GIGGLING GOOSE PRODUCTIONS, INC.

Then, a tan goose flies across the text, laughing very weirdly.

Variant: On Homeroom, after the standard animation of the logo plays, the words "in association with" appear on the same background as the logo before going on to the Castle Rock logo.

Technique: The goose flying past the logo.

Music/Sounds: A soundbite of laughing from the goose (hence the logo's title).

Music/Sounds Variant: On later prints of The Seinfeld Chronicles, it's the end theme followed by the goose laughing.

Availability: Rare. It's seen on the Seinfeld pilot The Seinfeld Chronicles on the DVD and some syndie TV airings. This also appeared on the pilot of Heart and Soul which is long gone outside of tape-trading. It was also seen on the 1989 sitcom Homeroom, the only weekly show this logo was on. Might have appeared on the 1988 pilot Home Again, co-produced by Warner Bros. Television, unlike the other shows, which were produced by Castle Rock Television.
