here's mine:
A chain is only as strong as.............the bhp of your bike
A friend in need is a................pain in the arse
A journey of a thousand miles begins..........at the gas staition
A little of what you fancy......................gets you divorced
A penny saved is a............waste of time
All work and no play makes.............you knackered
All good things come to he who..........has the most money
Cold hands, warm.............cock (well I had to)
Great minds think............shit, lets get Outta here
