Horatio Nelson (1758-1805) was a British admiral whose naval command prevented Napoleon's invasion of the United Kingdom.
In the It's Wolfgang Amadeus Mozart sketch the TV show "Famous Deaths" closes with the supposed death of Horatio Nelson. A clip shows the admiral being thrown out of a window and crashing on the ground saying: "Kiss Me Hardy". (In reality he was shot during the Battle Of Trafalgar.)
In the Film Director sketch, director Martin Curry has produced an adaptation of the Battle of Trafalgar where all parties involved have enormous front teeth. A clip is shown from the moments where Admiral Nelson is dying. He requests Hardy (who has the largest teeth of all) to put his hand on Nelson's thigh, as opposed to the kiss (which would be impeded by the large teeth).
