Overheard in the toilets - schoolkid walks in, screws up face and says "uuagh, smells like someone crapped themselves in here". From a cubicle a little way down comes a voice "Mate, it's a 5hitter, what were you expecting, roses?"
Strangest sights- on leaving the rest stop just before the top of Lavers Hill, I young guy on a road bike didn't have enough forward momentum on cleating in and "pancaked" in front of everyone. He was back on the bike in a flash and his second attempt was successful as he disappearred rapidly without looking back
As a riding marshall I saw a few funny things. Best was on Day 4 when I was directing traffic - called a group of riders to stop at an intersection, old mate on a nice roadie rolls up slowly, says hello to me - then falls over to the right still clipped into his pedals! The cop on point laughed - I had the good manners to help him up and refrain from giggling until after he pedalled off. Fortunately nothing more than his ego was bruised.
