When former American President Gerald Ford - probably more famous, on this side of the water, for his character in The Simpsons - took office he didn't realise his first speech would end being used to bid farewell to David Letterman 40 years later.
Letterman brought his 33 year Late Show career to an end last night, in what was an emotional farewell. He thanked just about everyone apart from myself and yourself.
Of course, the highlight of his years on the show, will always be this. We'll miss you David.
