Most Offensive Song Contest

From OAPedia.com

The Most Offensive Song Contest was an Opie and Anthony contest where listeners recorded offensive songs (involving racism, pedophilia, etc.) and sent them into the show.

The bit was inspired by the song "Full Blown AIDS", performed by Stephen Lynch and co-written by Lynch and Jay Mohr.

One of the songs from this contest was played years later on Howard Stern's show, effectively ripping O&A off ("Hoo hoo hoo").
