Oscar

Oscar was your next-door neighbour and you both had cats. You had a female cat while Oscar had a male cat.
After some time you noticed your cat's belly had growing quite large, and you just thought she was getting fat until one day she gave birth to six cute little kittens.
But then you noticed that the little kittens looked a lot like Oscar's cat. Then you heard your doorbell. You went and opened to only find cat supplies in a gift basket with a note saying 'Child support.'
