But he wanted to take grandma when he learned she missed her own prom because she couldn't afford to go.
Cody took his girlfriend and his grandmother out to dinner before Friday night's big dance.
Granny can't boogie like she used to.
But she tells a local TV station she wasn't going to let recent knee surgery keep her off the dance floor.
