Oh, yes. You'll need the combination and the countersign to the password.

The Password is "Yomomma" and the countersign is "Saywatsucker", random groups of letters chosen for their randomness. The combination is 2 turns right past zero to 46, 1 turn left past the first number to 107, and then right to 3. Failure to use the right combination, or even making a mistake, will cause this ahem! rather large check to ignite and you will only have a pile of ash -- I suggest having the person who will open the container practice.
