Lunatic asylum Puns

An Official is inspecting a lunatic asylum to find one inmate to be released for the Asylum's anniversary, after several hours of visiting the numerous wards he enters one where he finds a man sitting on his bed carving a wooden block. He approaches the man and asks him what he was carving, the man on the bed replies that he carves wooden clothes pegs, and that each day he makes around 5. "Well that certainly is impressive" the inspector tells the man, "I think I shall recommend you to the warden for release." The inspector then notices a man hanging from the ceiling, "What is he doing up there?" he again questions the man on the bed. "Oh, he thinks he's a light bulb!" The man on the bed replies, "Well, shouldn't we get him down?" the Inspector asks, shocked, "Don't be daft!", remarks the Man on the bed, "I can't work in the dark!"
