After the event a marshal who witnessed the whole affair comes up to him and says "Fred, that was jolly desent of you, sacrificing your chances like that!".
Fred replies "Well I was married to her for forty years."
Tandem rider says 'Well, this bike holds a lot of memories for me. My wife and I spent many happy hours on this tandem, and now that she's dead I still ride it for those memories.'
Single rider replies, 'That's really deeply touching. But surely there's someone, a close friend or a family member, who would understand your feelings, and who you could invite out to ride it with you?'
'No', says the tandemist, 'they're all at the funeral'.
