Ushers don't sing...
Riley Freeman: [laughs at Tom] Usher? That dick is *my* age!
Tom Dubois: So, you guys don't think I'm overreacting?
Robert 'Granddad' Freeman: I don't think so. You a big-time lawyer, and Sarah's acting all crazy over an usher?
Huey Freeman: Not *an* usher. Usher, he's a singer.
Robert 'Granddad' Freeman: Usher's ain't supposed to sing. You can't hear the movie!
