From what I recall--
People are shooting off the potato gun (mostly granite_embedded, as nearly nobody else was sober enough, skilled enough, or foolish enough). Moonracer's son is eating a raw potato and drinking a beer. Potatoes get shot in the general direction of the highway. Biodiesel is added to the cannon, and shortly thereafter a white SUV tears through the parking lot. Repeatedly. Chucker gets lit off, and short guy in white suit throws SUV in reverse, steps out and yells, 'YOU CAN'T DO THAT HERE! GUESTS ARE SLEEPING!'
I may have this exchange caught on video.
