I know a guy who always leaves the back doors of his van open. One day a customer's chicken got into the back of his van and he didn't realize it. He closed up the doors and started to drive off when all of a sudden the chicken starting flying around the back of the van and making tons of noise. He had to stop in the middle of the road so it could get out.
