Hey, hey, hey - I'm often invited to those kind of things in my circle because I can cook like a mo-fo. I'm great with kids and old folks. I know to selectively misbehave/behave. And since we are in the Jesus thread I'll mention I've also served as a worship leader at a place that ran over 1k of bodies every Sunday and have done hundreds of solos and leads at churches, funerals and charity events.
Hard-core sinners understand grace the best.
