Prosthetic Lips is a 23-track tribute album honoring Weird Al Yankovic. It was recorded in 1996 members of his newsgroup, and was initially released on cassette and later on CD.
The album sold out long ago. No more pressings will be released, but it is available for download at the Zelda and The Unibrows site.
