I ask you: how can a list of ten awesome Sesame Street moments not have Put Down the Duckie?
This is why Top Ten lists are so hard to do. You forget stuff that should be right at the top.
And if you don't recognize at least some of the people on that video, then you need to turn in your geek badge. Though even I'll admit having Jeremy Irons in there is at the very least very creepy. This is, however, well offset by the inclusion of Yosh Schmenge.
