please don't fuck the threads, people. it's unethical, distasteful to passersby, and just plain unhealthy.
simply put, when you fuck a thread, you essentially fuck everyone else who has fucked, is fucking, or will fuck the thread. nasty fuckers!
plus, think about your reputation! do you really want to be known as a thread-fucker? no way!
and what would your grandma say if she knew? you know, if she's dead, she does! she's looking down from heaven. every time you fuck a thread, your grandma's wings furl just a bit more.
