Many of Dave's speaking breaks and the "Hot for Teacher" video.
Also, his non sequiturs after the second chorus in "Unchained". The entire break in the song is a jab at the clothing choice of longtime producer Ted Templeman. It's Ted himself who says "C'mon Dave, gimme a break..."
Most, if not all of Dave's talky parts boil down to CMOFs, in the end.
What about the "music video" for "Everybody Wants Some!!" in the film Better Off Dead? This troper can't think of that song without thinking of the movie scene.
The acoustic first half of "Ice Cream Man" may count too.
