#1 Pineapple Express
Hilarious action comedy about a stoner and his dealer (played by Seth Rogen and James Franco, respectively) who have to work together after they find themselves in a huge mess because one of them witnesses a murder by a drug baron.
#2 Hot Tub Time Machine
I watched this not knowing what to expect and I was pleasantly surprised. This movie is about four men that are transported back to their 80's teenhood. They then have to find a way back to the present without changing anything major in the past if they don't want their lives to change drastically in the present. Probably not a top tier comedy, but it was a good laugh anyway.
Funny comedy about two teenage friends (played by Jonah Hill and Michael Cera). If you want an idea what to expect from this, then I'd compare it to the American Pie series, but with less focus on the sex and more on the general teenage life/partying.
A superhero comedy about a regular guy that wants to be a superhero. Has a decent amount of really funny scenes.
Hope this list helps you out a bit when looking for new movies to watch!
