This is a video montage of 100 of Youtube's "greatest hits" in a scant 3:24. I recognized most of them, but there were some I hadn't seen before. And those, my friends, were the sucky ones.
NOTE: It's best to stop after the Leroy Jenkins clip. It's all downhill from there.
Thanks to Harry, who was responsible for at least 10 of Redtube's greatest hits.
