An atheist was seated next to a young girl on the air plane. After taking off, he turns to the girl and asks: Do you want to chat? The journey goes faster when you have someone to talk to.
The girl answers – What do you want to talk about?
The atheist – Oh, I don’t know. What do you think about that there is no god, heaven, hell or life after death?
OK – the girl answers – but let me ask you a question first.  A horse, a cow and a deer all eat grass.  Why is it that the horse poops lumps, the cow poops slushy patties, and the deer poops small, hard pebbles?
The atheist, surprised over the question, thinks for a while and then says – Hmm… I have no idea!
The girl – Do you really feel qualified to discuss god, heaven, hell or life after death, when you can’t explain shit?
