When you see Mike Winfield, the first thing you notice is his eye-catching, winning smile. But that’s a curse, he says. You see, he’s plagued with big teeth and he can’t close his mouth because it hurts. Because of this, he can’t act tough and everyone thinks he’s just a nice guy. Nice or not, his self-deprecating humor is pretty hilarious and he fires out his witty quips. Other topics for laughs are his dealings with his older stepson (he calls him a “step-man”), his past days working for a grocery store and the rampant theft in the self-check lane. He takes the Hilarities stage tonight at 8 with additional performances scheduled through Sunday. Tickets are $18 to $20. (Trenholme) (Trenholme)
