I was very skeptical but Knocked Up was actually a pretty cool movie Had a lot of pretty funny stuff and there is even a shroom sequence. I had fun watching it.
As for horror I like the slasher stuff. Many can be so predictable but there's a fairly new one called Behind The Mask: The Rise of Lesley Vernon. This movie is awesome it takes all the slasher cliche and turns it on it's ear in a very creative way. Lot's of funny stuff. Watch it high!!!
