That reminds me of when the first time I used Capsaicin, I had the ole lady rub it on my shoulder and told her the label says " wash hands thoroughly after use ". she said she was getting a shower anyhow, lol, boy did she come out of there cussing after that stuff hit some naughty parts.
I still laugh about it today and she still cusses me for it.
If you don't know what capsaicin is made of, Hot Peppers.
