Everything Must Go (starring Will Ferrell) -
Boy: Are we friends?
Man: Yeah. Yeah, I guess so.
Boy: Remember when I told you I tried out for the baseball team?
Boy: I lied. I don't play sports.
Man: Why not?
Boy: They make you change in your locker room.
Boy: The other kids make jokes.
Man: What kind of jokes?
Boy: They say, “You're so fat, you got shocks on your toilet seat. You're so fat, if your arm broke, gravy be coming out.”
Man: (Laughs) That's mean. Have you heard this one, “Your momma's so fat, she heard it was chilly out, she ran inside, got a bowl.”
Boy: “Your momma's so fat, she has to shower at a car wash.”
Man: “Your momma's so fat, she has 101% body-fat.”
Boy: “Your momma's so fat, you have to roll her in flour, then dive for the wet-spot.”
Man: Do you know what that means?
Man: Yeah, maybe don't tell that one.
