How to Get Strangers to Do Almost Anything with You
Make sure to have your scavenger hunt list look legitimate. Print it out with professional type font and have an "Official Liver Disease Research Scavenger Hunt" header on top of the page so people have no reason to doubt you. It also helps to have someone else going around doing the same thing. If you can get enough likeminded people involved you can even start up your own totally real scavenger hunt and put one of everyone's weird ass activities on the list so they can then do that with the people they choose and it's a lot of fun.
It's important to remember this isn't illegal necessarily because you're only doing things that other people will consent to. If someone doesn't want to eat a Slim Jim out of your ass then they don't have to, but if they volunteer because they think it's for a good cause there's nothing wrong with that as long as they never find out and there's really no reason they ever should! So take your weird ass non-sexual stranger fantasies out onto the street and have fun. Or beware people who claim to be in scavenger hunts and ask to see proper ID and credentials before you assist them in cleaning their ears out with q-tips because you think it's to cure Sudden Infant Death Syndrome.
