Xanthippa's Chamberpot

What’s the integral of one over cabin?

Log cabin! (…plus C)

And since that one was so short, here’s another one:

A carbon-11 atom walks in to a bar, stares at the bartender for about 10 minutes, then orders a double whisky and instantly starts sobbing.

“What’s the problem, buddy?” the bartender asks as he delivers the drink.

The carbon-11 atom responds “I’m having a half-life crisis.”
