In a stiff competition, The University of St. Thomas in St. Paul, MN has won the contest for most absurd example of campus liberal intolerance. Clearly this was inspired by the Geico "Hump Day" ad. It's one thing for a couple of morons to find this racist. It's another for them to actually get the event cancelled.
Seriously, after a friend sent this I googled it to make sure it wasn't a spoof. Good Lord, it isn't.
