Do you like doing both AT THE SAME TIME?
If so, then get really high and watch Smiley Face.
Anna Faris is the protagonist, Jim from The Office is in it, Seth from the O.C. is in it, that really funny lady from 40 Year Old Virgin (the boss lady) and a bunch of other movies I can't remember because I'm high right now. And some other people, whatever, I linked to IMDb right up there.
Basically, Jane (Anna Faris) gets really high while playing video games. Then she gets really hungry, so she eats cupcakes her roommate baked that she was expressly forbidden to eat. All of them. Surprise! They are weed cupcakes, so now she's incredibly high, and has this huge misadventure.
It does a really good job of showing what it's like to be way too goddamn high. If this sounds like something you've ever experienced, then you'll probably be able to relate.
Anna Faris is hilarious, and it's so awesome to have a stoner comedy featuring a woman stoner.
