By the police once when there was a group of us on a pub bike ride, we all went in sepreate directions, I made a dash for it on the footpath over the fields, riding so fast that it would have made Hoy look slow (in my alcohol fuelled mind anyway). The footpath runs parallel to the road so I switched my lights off to go into stealth mode. Que a big splash as I went into the ditch by the side of the path. Two of the others got caught and taken to the nick, one was charged (ended up in the magistrates court with a £300 fine)and the other was let off with a good bollocking. We still laugh about it now.
