Feb. 5 Groundhog Prom Sokol Auditorium, 2234 S. 13 St. 21+, 8 p.m.-2 a.m., $8 ADV/$10 DOS 346.9802, groundhogprom.com Thirty-three years and still jesting? Yep. Omaha's annual gathering of merry pranksters continues Saturday, and this year’s culturally relevant theme goes by the “Wiki-Licious Costume Ball.” Due to the recent WikiLeaks uproar, you're encouraged to wear something “transparent.” In case you haven't been before, people don satirical costumes that touch on recent social or political themes, but plain old nonsensical always seems to fit in, too. Satchel Grande again take the main stage along with Funk Trek. Sokol Underground plays host to The Bishops.
