A cop arrested a Paddy for smoking on a Dublin bus.

"Can't you read that sign? that says No Smoking" said the cop

"No"said Paddy who had supped one too many! "I can't read"

"What's your name?" demanded the cop, but all he got was a mumbled reply.

"Write it down"said the cop handing him a notepad.

Drunken Paddy scribbled something illegible.

"What's that?"said the cop.

"I don't know"said Paddy "I told you I can't read.
