Quote from Fez in Black Dog
Fez: Okay, I washed. But the ink isn't coming off my little man. Help. Kelso: You should try bleach. Donna: Ooh. Or Comet. Jackie: Yeah. Or steel wool. Hyde: Hey, and if all else fails the one thing that gets out ink is more ink. Eric: That's right, Hyde. Whatever you do, use the steel wool first. Really scrub so the soap gets in there. Remember, if it doesn't sting, it's not working.
