When the owner of Granddad's house invites Granddad and the kids to his garden party, Huey tries to start trouble by saying Jesus was black and comparing Ronald Regan to the devil. Meanwhile, Riley and the owner's grandson (a soldier back from Iraq) play with guns and Granddad runs into the self-loathing black butler Uncle Rukus.

Huey and Riley try to convince Grandad that his new girlfriend Cristal (like the champagne) is actually a prostitute. Of course, Grandad doesn't believe them, even when she spends all his money. But when A Pimp Named Slickback shows up, the truth is revealed.
