Hat trouble

A guy’s walks down the street when a strong gust of wind blows his hat off.
When he finally catches up with it a dog is chewing it. So the guy complains to the owner, “Look at that!”
“What?” the owner replies.
"Hey! I don't like your attitude!" says the guy scowling.
"It's not my 'at 'e chewed, mate. It' yours!"
