The Monkey

In our house we have a different bathroom set-up to what we're used to.  The set-up for both bathroom is that the toilets are separate from the actual "bath"room.  The upstairs is beside the room with the shower and the tub and the downstairs one is beside the washing machine and laundry sink.  This is similar to a lot of European homes and works quite well.
In the downstairs W.C. when you close the door there is a black chimpanzee sticker on the wall that stands about 3.5 feet tall with a sign that says "Laugh now but one day we'll be in charge".  It's the best bit of whimsy in the house in my opinion.  It also is extremely convenient because instead of asking the kids if they need to go potty we can say "Go visit the monkey."  This is infinitely more fun and the kids think it's awesome and are more interested in going.
From upstairs I just heard Cian say "Dad you set up the game....Monkey I MISSED you." All sorts of awesome.
