Speaking as someone of Irish ancestry, I don't know of any other name for a paddy wagon than, uh, paddy wagon, so I'm not sure what they wanted him to say. That being said, the last thing we need is more talk about anything Irish. The celebration of all things "Celtic," by people who wouldn't know a Celt if they ran across him in any of the regions of central Europe the Celts historically inhabited, has gotten right out of hand.
