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 ;-) )
