not my joke, but funny

It's September 12, 2001. You're sitting in front of a TV, watching footage of the World Trade Center collapse over and over and over again.

All of a sudden, someone from seven years in the future walks out of a tiny temporal vortex, and tells you: George W. Bush is going to fuck this up so badly that in 2008, the United States of America will likely elect as president a black man whose middle name is Hussein and whose father was Muslim. Oh, and he also admits he's used cocaine.

I think it would have been easier to convince me of the reality of time travel. "No, no, I believe you really are from the future. But the other stuff, that's CRAZY."
