I've googled this multiple times, and I know for a fact I'm not crazy. When I was in high school (2006-2010), one of my friends and I would relentlessly quote this one animation from what I believe was Super Chunk, a network variety show. The animation has a walking, talking dollar singing about how awesome he is. He drives a sports car with money pouring out the sides, and has run-ins with other currency portrayed by semi-racist stereotypes (classic example: the Mexican peso is hired by the dollar to do work for him, and the peso just responds with, 'trabajo es trabajo,' in the classic "lazy Mexican" style. The opening lyrics are something along the lines of, "Oh, I'm the Mighty Dollar, nothing's ever gonna hurt me! I am number one...the best darn currency!"

Can anyone help me find this? I'm shocked that I can't find a single trace of it on the interwebs...

Thank you in advance!
