Heres another one sent from Cacksy;

Paddy Reilly was walking up the High Street with a monkey on a lead when a policeman stopped him.
"Where are you going with that beast?"asked the cop.
"I'm taking him to the zoo"replied Paddy,which satisfied the cop.
Next day the same cop stopped Paddy who had the same monkey on a lead in the High St.
"I thought you were taking that thing to the zoo"said the cop.
Aye i did, and we had a great time, so i thought today we'll go to the pictures.
