A great way to do gross outs

We just got back from our fall retreat.  As such, one of my favorite elements is always the Saturday, late-night special.  It's the time when we do the wheel of torture!  We set it up somewhat like a game show, you could go all the way and get costumes and what not, but we just have two guys they interview the "contestant" up front and generally serve as the personality of the time.

I'm not sure who came up with this, but I first saw it at a Nazarene teen camp in New Mexico.  The idea is pretty simple, but loaded with fun.

1. Create a display wheel.
   I'd advise building one that is easily viewed by the audience, this would allow you to gauge the size you'd need to create.  Go for one that could be placed on a stand or tall table.  We had someone (thanks Alan Stewart!) make the wheel with three 5ft legs so that it stood eye-level.  Next you'll want to place nails or pegs into the wheel and a "ticker" to flick off each peg so that there's something to catch (create friction to stop) it.  Go ahead and mark the section of the wheel with lines.  We numbered it to 13 because it was for gross-outs and wanted to play off the unlucky thirteen.   
2. Find your content
   There are limitless sources for quick mini-games.  If you're in need, here's two easy ones:

   http://www.thesource4ym.com/games/sick.asp
   There's always going mega-insane with stuff from NBC's Fear Factor.  I'm NOT recommending this as phone calls from disgruntled parents or their lawyers are never fun. 
3. Gather your supplies and set up crew
   Get your supplies well before you start!
   Don't put yourself or others in the position where you'll need to run to the other side of the building to grab something.  Pull it all together and organize it in advance.
   The "set up crew" is almost a no-brainer, but I figured mentioning it would save a youth leader or three.  If you're participating as the personality up front that is calling people forward (playing the game show host), then you'll have a hard time ALSO doing the set up and supply organization. 
4. Get rolling!
   At this point your ready to spin the wheel and let the good times roll... straight on to YouTube!  Just kidding... maybe... :)  We always mention right off the bat that this is completely voluntary, that no one is being forced to participate and that the results will be gross.
   We always do a sign up so as to make sure we have a list of willing participants.  We refuse to take someone's name just because someone else says it (Bobby can't sign up Frank, Frank comes up to volunteer or we don't put his name on the list).  This also eliminates the hassle of someone refusing to come forward.  They've agreed to it in advance, there's no forcing to be done
   They spin the wheel, land on the number and you tell them what they've won.  Repeat ad nausea!
5. Other thoughts and words of caution:

• the longer the set up and transitions the more you'll lose the audience interest.
• to intensify the night, you could have the different parties compete for points.  We did a battle of the sexes, worked great!
• consider busting these up to be a part of something larger, doing two maybe three at a time instead of the focus of a whole block of time.
• having a medical release for is always a good idea!  You never know what can happen.
• if pressed for assistance, you could drop some of the "set up crew".  It would take more up front work, just organize all the materials needed for the gross out that was spun and the participant could grab their own bag/box.  You'd still have to set it up, but some work would be done.
• follow the sage advice from my brother Derek Mitchell, "Always ask yourself; what I tell the police when they show up?"

Enjoy and please, feel free to share improvements to the idea!
