A mop with a key ataached to the top for any reason that you would need a key at the time you are mopping. Or at any time you may need a mop as you unlock something.
1. A strange man walkes up to you just as you are waling in the front door you then yell yay mop-key and and swiftly attack him with the mop.

2. You are mopping the kitchen floor when all of the sudden you realize that the door to the pantry is locked and you pull the key off of your mop and unlock the door for the family's sake.
