Work Crush: Sesame Street

I, like countless other people of all ages, grew up watching Sesame Street, and to this day hold a special place in my heart for it, and pretty much everything Jim Henson had a hand in. 
While it's difficult to whittle down my favorite videos, here are a few:

Frank Oz's laugh as Bert is the best sound in the world.

I loved Robin Williams, and while this video does make me a little sad, hearing the crew crack up at the end is amazing.

A Sesame Street parody of Twin Peaks? How can I travel back in time and be friends with these people?

While this technically isn't Sesame Street, it is still a really great parody.
