Lil' Kev lives with his mom. Lil' Kev doesn't drive.
While Dennis and Dee try to figure out if the rapper Dee is dating has a mental handicap or not, Charlie, Mac, and Frank try to start their own band without knowledge of how to play musical instruments.
Dennis antagonizes Dee further when he says she can date whomever she pleases, but she should ask herself if she really likes Kevin or if she's only gold digging a retard.
Dee lets it slip that she's picking Kevin up in an hour.
He remembers Kevin attended special needs classes in elementary school. Now, with Dee on a mission to prove her brother wrong, Mac has a pitch for the gang.
They need to start their own band, because if a retard can do it and get laid, they certainly should be able to!
Dee dumps him and later discovers he is not in fact retarded when he slams her during a rap song.
