A Cabbie runs into a bar and sees his friend Doctor Miller there.
"Great! I need to talk to you Doc. First, Bartender, bring me the strongest drink you got!"
"What's the matter, George!"
"Doc, how big does a penguin grow? I mean, is it up to your waist, to your shoulders or what?"
"Don't know for sure but the ones at the zoo are about waist high, a little taller."
"How about 5 foot ten and 180 pounds?"
Nope, never heard of one that size before."
Bartender. Pour me one more drink and some mints if there's any here. Then, call the cops. I just ran over a nun!"
