How about some Art History
This guy is the worst painter I have ever seen, I mean look how he uses way too much paint just blobbed on in some places and really thin in others, man this guy sucks as a painter.
And what's up with that thing on his ear?
For someone like me (art major, visual person) seeing this stuff in person is a big thrill.
Seeing the reaction on the other people in the rooms faces when you make the comment above is priceless. Sometimes they know you are just pulling their legs, and others are dumbstruck, it's great.
