14 Approximate number of feet between Fat Tuesday's railing and the ground. The moral: Don't piss off bouncers.

40 Number of days in Lent, the period of sacrifice beginning Ash Wednesday that is traditionally celebrated by Philadelphians by drinking one ounce of Hurricane Malt Liquor for each day until Easter Sunday. The moral: Brace for the smooth taste!
