When we loaded up to go to the 1994 Car Wash Bowl (our unofficial motto: "hey, it's a bowl game!") in Miami for New Years, things were a little sensitive, and we wanted to try to avoid any nasty drinking incidents that might serve as ammunition for our political adversaries in future battles. That in mind, we loaded the bar onto the bus a couple of bottles at a time, stowed in people's carry-on baggage, which was kind of a pain in the ass, but we figured hey - we can make one concession.
However, all the mixers were carried on quite in the open. All the 3 liters of Coke and 7-up were fairly inconspicuous I guess, but probably not so the gallons of collins and tonic and bloody mary mix, and the lemons and limes and grenadine and Roses and 80 pounds of ice (in retrospect).
So, anyway, to get to the joke: we were just about to pull out and the driver comes over the intercom: "As we are preparing to leave for this 14 hour drive, I couldn't help but notice the large quantity of... mixers being carried on. Now, this is very important, I only have ONE RULE [loud whimpering and groans from the passengers]: No Booting On My Bus!"
[Loud huzzas]
(In Miami we made sure and got the drivers a nice bottle of 14-year old bourbon for New Years.)
