I'm not sure what the JCB song was, but I still liked this parody. The prez was drawn a clueless little kid and had the right word choice. I'm generally a moderate (liberal on social issues, conserative on economic issues).
Oh, and KkazakK, no one said GWB causes global warming, global warming wasn't even mentioned in the song. All the song wait was GWB does actively try to stop pollution.
