The moment in which Girl Talk mashes up Ahmad's "Back in the Day" with Rod Stewart's "Young Turks" during "Shut the Club Down"? Too damn genius.
Likewise with Thom Yorke being edited to look like he's singing Blackstreet's "No Diggity" (during the second video, which is based on "Still Here," track 3 from Girl Talk's Feed the Animals album). I don't know who edited these music video clips together to GT's Feed the Animals tracks, but somebody get this guy an editing award.
