Some know him as Tom Haverford from Parks and Recreation, others recognize him from his small-yet-memorable characters in Funny People, Observe and Report or Flight of the Conchords, while longtime fans (ahem) still quote his hilarious sketches on Human Giant, but his stand-up trumps ‘em all. Saturday, the dude who has everyone “treatin’ they selves” performs at the Aronoff Center. From his family to celebrity encounters to everyday observations, Ansari brings the LOLs. Hopefully his alter-ego RAAAAAAAANDY will make an appearance. Go here to get tickets to tomorrow’s show, which begins at 7:30 p.m. Second Sundays on Main also makes a return this weekend. Hop around OTR as you enjoy live music, food, beer and local shopping from noon-5 p.m. Sunday.
