Halloween is recently being celebrated in Germany, sadly not in the time when I was growing up, but oh well. So he was preparing Halloween decorations with his kids and created these cute bats:

Step one: put finger paint on tiny kids hands

Step two: make the kids put down their hands on the paper and make sure they don't move their hands

Step three: Paint a tail, legs, eyes and mouth

And tadaaa, you got a silly ol' bat flying around like it's supper time.
Brilliant!
