right heres a dare, prefably for men, get around 10 pairs of underwear, mke them embarresing ones to be seen in like cartoon breifs or even girls panties, attach ur pants to a rope by the window or doorway so other people passing by may be able to see, tie your hands and feet if possible, like this:

then let your self hang there in some embarresing underwear until :
1) the support gives away
2)you manage to break free
3) someone finds you
if you want to spice it up, do somthing messy. i have tried this and actually got pictures taken of me lol, was great fun but also embarresing, be sure to wear a hat of some sort so none knows who you are
if some one wants to see me do it on webcam then pm me!
good luck guy and girls
