Hmmmm. What to do? Supposed to act like a know-it-all who can handle anything...
Of course I can! I can call all kinds of mechanics and help relieve your stress with cunnilingus. Can't argue with that for a fix, can you?
As for whether or not I could diagnose the problem, I guess my advice would be to try unplugging it and plugging it back in.
Short Answer: It's a good thing oral sex solves all problems, otherwise I'd be a real useless twat.
