Superglue

[onestrangeguy]

Rather than gluing clothespins to your nipples, which might really start to hurt if the glue didn't release in the desired time, I'd suggest starting with something benign like gluing your nipples to the wall.

Careful there, that almost sounds like a fun idea...
After all,the nipples won't be smashed by the clothes pins...

P.S. to make it more fun, stand on your toes while the glue sets...
And while you wait, think of what to tell your rescuers...
