I'm sorry but I must have the worlds worst recall for names so I'll try and describe a couple.
One magic trick basically you have three envelopes of different colors, you have 2 volunteers come up to particiapte they each choose an evelope and if they guess the correct one they win $1. [of course you win the $] but the spill goes something along the lines of if they choose the first one -- oh so you choose the easiest one, many do they take the easy way out, middle one - is the statically that most would choose so---you go with the crowd, you do what most people would do. I can't go into how this one works but if your interested pm me and I tell you were I got it.
One skit that could work we use as ministry is basicall called [the painter skit] basically two clowns are painiting a room and a third one inexperienece keeps trying to get included, and whe they go off to lunch, he gets into the paint, evenually getting stuck in the bucket, then on the floor. as we do this as a message skit, one clown gets and oversized bible and we pray and the person becomes freed. "For all have sinned and fall short of the glory of God", but you could use the choices/consquences in the skit. Try
www.clown-ministry.com they have skits on there they allow people to use.
