Because he's a dog. Dogs cannot drive.
Stays up all night pondering the existence of a dog
A sub-woofer! Thank you, I'll be here all day.
Because he found it to be SUB-standard.
Because he could only say, "neighn!"
Because he was driving her buggy.
When you swerve to miss a tree and then realise it was your air freshener..
He left his foot on the clutch.
A yellow license plate.
