paddy wagon
A dirty van cops use to carry prisoners. It used to be called 'P. D. Wagon,' and people started calling it 'paddy wagon' because it sounded funny.
The cop said, 'You’re going in the paddy wagon, you stupid fool!'
He got so angry he tried to punch the cop through the paddy wagon window.
They put the whole gang in the paddy wagon and forgot to take them out.
