For 11 years, Clevelander DJ Kishka hosted a Polka Happy Hour at the Happy Dog Tavern. He launched the event in 2005 with an impromptu polka jam after a polka band that was scheduled to play didn't show up. Two years ago, Kishka brought the monthly event to an end. But he comes back to the Happy Dog tonight for his annual How the Kishka Saved Christmas happening. He'll put up a fake Christmas tree with sauerkraut tinsel and hand out pierogi ornaments to be colored and hung as well. It all starts at 6, and admission is free. (Niesel)
