Paddy is in a DIY store looking to buy a bath. After looking at a few, he decides on the one he wants.
The day after, he storms back into the shop.
'Oi you!!' he shouts at the assistant. 'This bath you sold me is faulty, I can't get it to fill!!'
'Didn't you buy a plug?' says the assistant.
'You tw@t' says paddy, 'You didn't tell me it was electric!!!!'
