In honour of the Penis Bandit who ran across the stage at his High School Graduation, I thought it would be appropriate to have a thread honouring other great pranks.
There are a few that stand out in my mind that I've stumbled across on the internet:
The cal-tech prank is absolute genius...not sure if it can ever be topped.
The crosswalk one on the other i just find annoying. Definitely feel for the drivers in that one...
