Many a reader of this site has suggested I mention the following. In the "Weird Al" Yankovic video to which I linked early this morn, the guy in the car at the end is Greg Kihn, who wrote and performed the original song being parodied. It was called "(Our Love's In) Jeopardy." Curt Alliaume suggests this may have been the first time a musician appeared in a video that parodied his song.
