As Evil Force said, spike the Shasta every 15 minutes and:
Bring a gas grill, cooler, and boom box and start setting up during the drama.
Take a few fake falls down the steps and just lie there moaning - make sure they smell the alcohol on your breath.
Bring a friend, or 2, get into a brawl during the main talk shouting obcenities about the WTS rendition of John 1.1.
Stand up, scream out, and start speaking in tongues.
Walk on stage in a zoot suit and ask who is presenting the award for salesman of the year.
Just start pissing on the wall and tell the on-lookers that Joshua left one man to piss against the wall.
Bring your birds and cats, bring your crazy neighbor, bring the lonely derelict, bring a party.
This thread has made my mind up: I can't wait for the next D.C. - anyone have the Canadian schedule? This will be fun, maybe I'll tour a few of them, like years ago going on tour with the Dead. After 2 or 3 DCs I should be able to go up on stage and give the damn talks. Life is looking up! I'll take an attendant job, and maybe clean up after the sessions, fellowship with the flock, and have plenty of pictures and stories for everyone.
