Fallon Thank You Notes: Rick Perry, Yahoo And 'Contagion' (VIDEO)

Much like "Late Night with Jimmy Fallon" itself, the segment Thank You Notes has gotten sillier and sillier as time has gone on. What started as a straight-forward segment about Fallon giving thanks to those that deserve it from the last week has turned into a freewheeling comedy ad-lib that includes sound effects, music and weird voices.

And we love the show for it. Watch the clips to find out who Fallon is thanking, but stick around for the bizarre sound effect pantomime that Jimmy and announcer Steve Higgens act out.
