Early philosophers often engaged in debates concerning the nature of humor, posing each other enigmatic questions beginning with “What’s the deal with” and ending with “Am I right?” Indulge in classic rhetoric with this deal to see Colin Mochrie & Brad Sherwood: Two Man Group at Lowell Memorial Auditorium. For $25, you get one ticket for Friday, April 13, at 8 p.m. (up to a $49.50 value, including all fees). Reserved seating will be the best available at the time of redemption.

Longtime Whose Line Is It Anyway? stars Colin Mochrie and Brad Sherwood have toted their quick-witted, improvised comedy around the country for years. Not bound by scripts, the duo takes suggestions from the audience and fluidly bounces off each other’s screwball bits to craft hilarious scenes on the fly. As the evening rolls on, they draft game but uncoached audience members into the onstage action. Though audiences can expect daredevil games and easy patter between the two stage vets, the form of any given show won’t unfold until the night of the performance—as Mochrie reported to the Herald-Review, they’ve “developed an aversion to ever performing the same joke or routine twice.” Built in 1920 to commemorate World War II veterans, the auditorium suffuses even the most lighthearted events with a sense of history and the patronage of local bald-eagle populations.
