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 while your eye keeps winking!?"
