Jake Johannsen is a David Letterman darling. The comedian is one of the most frequent stand-up guests on The Late Show, chalking up more than 35 appearances. Hes also joked around on almost every other late-night talk show and had a few HBO specials. With an accessible style, Johannsen pokes fun at topics such as pushy vegetarians, succumbing to the forbidden fruits of Starbucks, airplane safety instructions and that ointment veterinarians give you to stop your dog from licking his sores. Its supposed to taste bad to the dog whos already licking his butt, he says. What could that possibly taste like? Worse than ass-flavor? Worse than dog ass-flavor? 8 p.m. today, 8 and 10:30 p.m. Friday and Saturday, and 7:30 p.m. Sunday. The Improv, 7620 Katy Freeway.
