Via PEEK, Washington Whispers provides some insight into what makes our Groper-in-Chief tick:

He loves to cuss, gets a jolly when a mountain biker wipes out trying to keep up with him, and now we're learning that the first frat boy loves flatulence jokes. A top insider let that slip when explaining why President Bush is paranoid around women, always worried about his behavior.
He should be worried. Do you think it's the "paranoia" that has made him pursue such an anti-woman agenda... and (until recently) prevented him from speaking out in favor of contraception and Plan B?

But he's still a funny, earthy guy who, for example, can't get enough of fart jokes. He's also known to cut a few for laughs, especially when greeting new young aides, but forget about getting people to gas about that.
