"Calculating statistics of injury" joke

A man (If you like, a blond) who often travels by plane calculates the probability of there being a bomb on any given flight. It's low, but not low enough, so the man always carries a bomb in his suitcase knowing that he'll be safe.

After all, the odds of two bombs on a flight are almost impossible!

BONUS JOKE VARIATION!!!

A man went to a hunting shop and asked if he could buy one bullet. The clerk thought for a second and said, sure, why not. The man gets his bullet and takes out a pen and meticulously inscribes his name on the bullet.

The clerk, watching this says, "hey buddy, why'd you write on your bullet?"

"Well, they say there's a bullet out there with my name on it, so I figured I'd better keep track of it!"
