when an interview is going bad all you need to do (short of dropping mammoth custom case mod on ones head) is grab the nearest person around the neck, prefereably a female receptionist, and threaten to choke a few people if they dont give you the job. Then tell em "so I'll start monday, should I bring my tools?" "I'm the best. I'll work circles around you people, I'll wrap you off the head with a f***ing ratchet!"
