With Cinco de Mayo this week (Friday), do the Hot Pepper Challenge. Get every kind of pepper from your grocery store and set them up most mild to set-your-mouth-on-fire hot. Invite someone to conduct a trivia contest amongst the show cast around Cinco de Mayo or Mexican trivia. Get the question right, and the cast member endures no pepper. Get the question wrong, and they must eat a pepper (start mild, work to hot to build tension).
