I think the funniest thing I have seen in my group (of many great moments in buffoonery) was after the party survived the Snowman soundburst trap and defeated the ice elementals at the frozen creek in SoS. The group still had to traverse the frozen creek which now had two great big holes where the party might fall through and be swept downstream under the ice (I played up the potential danger). After all the members carefully slid across using a rope system they concocted, the wizard (Alabaster Pennywhistle) triumphantly declared he would simply run and slide across in similar style to the famous Tom Cruise scene in Risky Business. He proceeded to take a running start and made a beeline slide across the creek on his feet until he got to the far side and crit failed his acrobat skill check and faceplanted into the snow bank on the shore.
