All righty, let's just start with the basics: it's an awesome movie. Go spend the 5-7 dollars to go see it! Just don't take ur parents ((SPOILER: you do see a cartoon dick for about 2-3 seconds)), cause there is a bit more crude humor than in the TV show.
My sister and I both went to see it, and it kept us laughing pretty much the whole time, mostly because of Homer.
Oh yeah, the whole line: "Sider pig, spider pig, does whatever a spider pig does. Can he swing from limb to limb? No he can't, cause he's a pig." The whole theater was speaking it with Homer when that happened.
