(HILARITY) Roscoe is a boy inventor straight out of an Encyclopedia Brown book. His dog Scampers can talk. The two of them upset history by drunkenly driving a Timecycle through the past, accidentally killing Abe Lincoln, and causing a randy zebra to bugger the baby Jesus to death. It's horrible; it's wonderful. (Theatre Off Jackson, 409 Seventh Ave S, 800-838-3006. 8 pm, $14.)
