Joe has always had an uncontrollable twitch in his
left eyelid since young. Fred has a splitting headache
and asks Joe to go get some aspirins. Half an hour
later Joe comes back with a dozen packets of condoms.

"I asked you to get me aspirins, not condoms."

"Yeah, I went to a dozen drug stores, but have you ever
tried asking for aspirin with a tic in your eye?"
