The Bleep Game
From OAPedia.com
The Bleep Game is the common name for the Opie and Anthony bit where the show staff takes an audio clip, and adds bleeps to various parts of it to make it sound dirtier and more offensive than it ever was before. This has been done to clips from Sesame Street and various news stories. The bit was popularized on Jimmy Kimmel's late-night talk show, and some fans accused O&A of ripping him off (Hoo hoo hoo). According to Opie, this is an old radio bit and was not originated by Kimmel.

The Song of the Count
Returning from the end of year vacation, on Jan 03, 2008, Danny brought the show "The Song of the Count", a Bleep Game video done using the The Count's self-titled song from Sesame Street. He admitted he had not done any work over the holidays and merely found it online. The song was played during the show and commented on and as the outro bit on the XM side.
