An old man woke up in the recovery room after an operation and said, ‘Thank God that’s over!’

‘You’re lucky,’ said the chap in the adjacent bed. ‘They left a scalpel inside me and needed to operate again in order to retrieve it.’

‘How terrible,’ said the old man.

The patient in the bed on the other side of the old chap stated, ‘They had to open me up again to find a sponge they had lost.’

Just then the door to the ward opened and the surgeon walked in. ‘Has anybody seen my hat?’

The old man fainted.
