My economics teacher once used the number 17 as a random number twice in one class, without noticing. A note on the number 7: magicians actually use the frequency of that number being picked for their tricks. If an amateur card magician asks you to pick a number, for example, "between 5 and 10" or the more daring "between 1 and 10" they want you to say 7. Now that you know this, though, I'd rather you humor us if you're ever asked..
