I had it happen in the middle of a Challenge, so I didn't even have the option of a do-over. Really put a damper on the celebrations, I must say! Thank goodness, no one was hurt. And I got to see my guests' real personalities. Everyone screamed and cowered and acted like total fools except teenaged Morty Goth. He grabbed a fire extinguisher (where was THAT hidden???) and had the fire out before the firefighters arrived. Go, Morty!
