There's another thread on this, but it's from last year and I hate clicking those little numbers. So I'll start with two things my friends saw:
-Security chasing some guy through a crowd, catching him and then forcing him to empty his pockets, only to find that his pockets were stuffed with pistachios. Tons and tons of pistachios.
-Two people having sex in a truly disgusting port-o-potty by the Sahara tent. Did not seem to notice when the door was opened.
