8pm Comedy

Calling all parody fans. The improv troupe Duck’s Breath Mystery Theatre is staging 25th-anniversary shows at the Arcadia on the Santa Monica Pier. The troupe, which formed in 1975 in San Francisco clubs and coffeehouses, went on to appear regularly on National Public Radio in addition to developing audio projects of its own--most infamously, “Ask Dr. Science.” Now they’re back--Bill Allard, Dan Coffey, Merle Kessler, Leon Martell and Jim Turner, that is--with a promised appearance by author-social commentator Ian Shoales, another former Duck’s Breath contributor.

* Duck’s Breath Mystery Theater. Today and Friday, Arcadia at Santa Monica Pier, Santa Monica. 8 p.m. $15. (310) 712-6362.
