Not that these two clowns need any plug since they are number one at the box office, beating Bourne, but if you haven't seen it, treat yourself and go see it.
I went a first time with JBoss friends on the day it came out. I saw it again with Nathalie yesterday, and she liked it. It doubles nicely as a date movie! So go. You have no excuses.
If you liked Knocked Up (Bill is there :) and/or Harold and Kumar go to Whitecastle (I was there) and even, if you haven't seen any of the two, just go see it this is outrageously funny. Be ready for out of control teen sex humor along the lines of the girl: "I am soooo wet!" the boy: "Yes, they said that would happen in Health class".
