Cognitive Comedy, a free improv comedy workshop for people with cognitive impairment and their loved ones, is back at Penn Memory Center. The class will continue this year without Leah Lawler, who left to pursue graduate studies at New York University, and is now under the guidance of Jean Haskell, who has taught theatre and performance classes for Temple University’s Osher Lifelong Learning Institute (OLLI). Improv actors-to-be can let it all hang out at Cognitive Comedy sessions each at 4 p.m. every other Tuesday between March 24 and June 30 at Ralston House, Room 241, 3615 Chestnut Street.
