creepy office guy
Co-worker who is extremely awkward, calls at home when you never gave him your number, and has no qualms about mentioning that he got the number from your payroll info. Shows up at your new job after you leave, and at the job of some of your other former-coworkers.
The creepy office guy never leaves a message with anyone if I'm not there. But he's good for hockey tickets, so I suck it up when I need good seats.
