A lot of women get their eyebrows waxed, as well as their moustache area. I had a friend 25+ years ago who weekly went to get her moustache area waxed because it was that bad.
Remember when those handheld home use machines came out that would catch and yank out the hair on your legs and other areas? It would take a long time, like 6 weeks, for the hair to come back and they implied that hair growth would reduce over time. They were pretty expensive when they first came out so i asked for 1 for Christmas pre Craig. OMG, it hurt like he//! I only used it 2 or 3 times on my legs and then gave up because it hurt so bad. My girlfriend asked to try it so i gave it to her and told her to go for it. She tried it for a few minutes, then decided to get plastered before using it anymore. She said that pretty much made it bearable. I told her to keep it and go for it, that I would stick with shaving or waxing.
They could use one of those on POWs or spies and they'd be babbling in no time just to stop it!
