Last time I was in hospital two other men in the same ward, an Irishman and a Scotsman, (no this is not one of those jokes), both had hernia ops with epidurals.
Not long after they got back from the 'theatres the Irishman decided he wanted to go to the toilet. He felt so good, he said, and could feel no pain he was going to walk to the toilet himself.
We tried to warn him not to try and walk as the epidural was still working but he ignored us, swung his legs out of bed, went to stand up and collapsed in a heap on the floor.
We were all laughing so much we could hardly press the buzzer for the nurse.
