A Bloke walks into the psychiatric ward of a hospital to visit his sick mate. He finds him sat up in bed, pretending he is driving his car and making loud engine noises.
"What are you doing?" asks the visitor
"I'm driving my Ferrari!" exclaims the patient
The bloke says "But mate,there's no Ferrari there"
Just then the man in the next bed shouts out "Shut up, you idiot! He gives me seven quid a week to clean that.
