Must See Frat Movie of the Summer: Knocked Up

"Knocked Up" is a Knock-Out"Knocked Up" may have only opened in theaters across the country this past weekend, but the move has already lifted itself to the level of some of the greatest comedies ever made.

The movie stars Seth Rogen, who you may remember as the outspoken friend of Steve Carell in "The 40-Year Old Virgin," for his on-screen banter with actor Paul Rudd. "Knocked Up" takes that banter and multiplies it by about 1,000 to create a movie that will keep you laughing through its entirety.
