Logo: On a black background, we see two boxers fighting each other. The one on the left wears shorts while the one on the right wears. The company name in a circus-like font appears below it. The one on the left then punches the right, before going back to its normal position. The logo is also shaking during all of this.

Technique: 2D animation and the shaking.
