Now that's fuckin' funny, I don't care who ya are.

Not exactly pot, but back when I was in my early 20s, I had a co-worker who had a sister that worked in one of the big hospitals in Houston. She would let her brother Dane know when shipments of nitrous oxide were due in, and would leave the mechanical room access doors unlocked. Two of us would come in dressed like the gas delivery men, pick up a cylinder (they were like 4 or 5 feet tall, big fuckers), and take it back to Dane's house. Then we'd call all of our friends and have what we referred to as a Bagpipe Party.
Price of admission was a Hefty trash bag, some rubber bands, and the casing of a Bic pen with the ink cartridge and writing head removed. Take the garbage bag and scrunch up the open end and stuff the empty pen casing into it with the writing end poking out, secure with rubber bands. Force the end of the pen into the cylinder's regulator nozzle and inflate the bag with laughing gas. Insert end of pen into mouth and "play your bagpipe" until you're rolling on the floor
When you've had enough and are ready to go about your day, sit back for about 10-15 minutes and breathe normally, then be on your way! No hangovers, no lingering buzz to fuck with your driving, and it's entirely legal (except for the stealing of the gas part)! Great fun!
