What are the most common numbers for a combination lock?

If you knew whose lock it was, I'd try their birthdate. 0422 for April 22, that sort of thing. Or the last 4 digits of their phone number. I would also try birth year. Say you were born in 1995, I'd try 1993, 1994, etc. as most locker users if its in a school have approximately the same birth year.
