At a mental hospital

At a mental hospital

A bloke is visiting his mother in a mental hopsital when in the same room he comes across a guy moving his arms around and making beeping noises.
"Excuse me", he asks him. "What on earth are you doing?"
"I'm driving my car!, says the guy excitedly. "Beep beep!"
"You fucking nutbar, you're not in a car, you're in a mental hospital!"
A voice comes from the bed opposite. "Mate, shut the fuck up will you, he's giving me twenty quid a day to wash the cunt."
