Everyone's coming up to me half in tears, 'Arj what about Global Warming — what about Climate Change and the planet?' and everybody's convinced that the earth has a problem — because it's so hot. But how come I don't hear a single intelligent individual aside from myself suggest the seemingly obvious possibility that the Earth is just fine thank you — but there's something wrong with the sun! 'Cause I'm not a scientist, but I'm pretty sure that son of a bitch is where all the heat is coming from. And all I'm sayin' is, when I burn my toast, I don't blame the bread. [crowd cheering] Wow. You guys really love toast jokes.
