Yep. How 'bout a workshop called "Skatin' On Fumes." A day-long or weekend seminar on how to live cheap. Take each indispensible expense someone is likely to have and explore how to get the absolute best deal or lowest price on it. Include empirically derived data such as, "This auto insurance is cheaper on the surface, but this company is famous for not paying its claims, so you'll actually be better off with this one over here that costs a bit more up front." Stuff like that.
