Dog food

A man at the checkout counter had lots of dog food in his trolly.
A woman behind him asked if he had a dog and what type it was.
"No" said the man, I don't have a dog"
"So what is the dog food for then?" She asked.
"It's for me" Replied the man.
"You eat dog food?" Asked the lady.
"Yes" said the man, "It's very healthy for you"
"Isn't it poisonous?" She asked, somewhat shocked.
"No", said the man. "Though it dose have a dangerous side effect"
"What side effect?" Asked the lady.
"Well, I was sitting in the road the other day licking me b####ks, and a car hit me"
