Elmo

Sesame Street did a parody of LMFAO's "I'm Sexy and I Know It," calling it "I'm Elmo and I Know It."  It's so cute and hilarious.

I also can't wait for the documentary Being Elmo: A Puppeteer's Journey to come out on DVD.  It's the story of Kevin Clash, the puppeteer behind Elmo.  You can see the trailer here:

My son does not watch Sesame Street regularly anymore, but he still lights up whenever he sees Elmo.  What's not to love?  Cute, small, polite, sweet, and forever 3 1/2 years old.
