I found this ad in a Tokyo newspaper and thought it was a fun idea. It reads:

Dr. Sketchy’s Anti-Art School puts the cheek back into life drawing. No drawing experience necessary. Just come down, sketch, drink, chat and have a blast! What. A burlesque-themed class, we combine cabaret, life-drawing sessions, complex costumes, smoking models and boozy fun! Fourth Wed. (Nov. 26) of the month, 8:30-10:30p.m. 1500 yen with a drink. Where. The Pink Cow, Shibuya. Phone (03)3406-5597. For info, send a mail to dillon@drsketchytokyo.com or visit http://www.thepinkcow.com or http://www.drsketchytokyo.com
