Fear and Loathing in Las Vegas...I don't know what genre to put it in but it's one everyone should see if you haven't.
South Park: Bigger, Longer, and Uncut even if you have seen it it's great to watch when you're in pain.
Thank You for Smoking is another good comedy/drama
The Maiden Heist is a good comedy
Tremors 1-3, 1 and 2 are the best, but 3 is alright
The Drawn Together Movie: The Movie
The Producers, I prefer the 2005 edition myself, but the older version is good as well
Any of the Futurama movies
Raising Arizona
Clerks
Rango
Them Idiots Whirled Tour, it's a comedy show with Bill Engvall, Jeff Foxworthy, and Larry the Cable Guy
Those are pretty much all comedies because...that's what I like so...yeah.
Also some advice from someone who got their wisdom teeth out not too long ago, for a few days afterward, try and keep lying down as much as possible. Sitting up/standing will have gravity pulling on your gums and it will hurt like a *****.
I also had a hard time the first time I changed the gauze against my gums, the lack of pressure made it hurt a lot for some reason. I don't know if it's the same for everyone but it's a warning just in case.
I hope your surgery goes well and you're not in too much pain.
