Okay, now I never got how John McClane did this (or whether I actually spelled his name right) so I give this to you.
You have a 5 gallon bucket and a 3 gallon bucket. How would you go about getting exactly 4 gallons of water into the 5 gallon bucket?

This is easy:
Fill the 5 gallon bucket completely...
Put as much water from the 5 gallon bucket in to the 3 gallon bucket, until that one's full (3 gallons), now you've got 2 gallons left in the 5 gallon bucket.
Empty the 3 gallon bucket, and put the 2 gallons that are left in the 5 gallon bucket into it.
Now, fill the 5 gallon bucket completely again.
Put as much water from the 5 gallon bucket into the 3 gallon bucket, until that one's full again (it was missing 1 gallon).
Now you're left with exactly 4 gallons in the 5 gallon bucket.
(Oh, and yes, you spelled his name correctly ;) )
