1) If you came of age in the late ’90s and had cable in your home, you probably remember Tom Green humping a dead moose by the side of the road and sneaking a cow’s head into his sleeping parents’ bed. Green’s wildly popular MTV show invented the prank comedy genre that’s been the lifeblood of network shows like “Punk’d” and “Jackass.” Fame based on infamy is hard to maintain, and Green couldn’t readily pull stunts on an unsuspecting public while on magazine covers. But he’s been surprisingly smart and resilient for a guy known for rubbing his butt on things. Green has built a mini-empire of podcasts and other online media and has a respected stand-up career. He also has a namesake beer, a milk stout brewed by Beau’s All Natural Brewing Company. His three-day stint at the Improv starts today. 7:30 and 9:45 p.m. 166 E. Bridge St., Homestead.
2) The 48th annual A Fair in the Park opens today in Shadyside’s Mellon Park. Promoted as a contemporary fine crafts and arts show and sale, it includes performances, concerts, food, and children’s activities.

Fair hours are 1 – 7 p.m. Free. Continues through Sunday. Fifth and Shady Aves., Shadyside/Point Breeze.
