A young man moves to a village in Wales and gets talking to an old man from the village.
He asks the old man what his name is; the old man gets very irate at this point and says:
"See that line of houses over there? I built them all, but do they call me Jones the house builder? Do they hell!
See those railway lines over there? I laid them all, but do they call me Jones the engineer? Do they hell!
See those bridges over that river? I built them all, but do they call me Jones the bridge builder? Do they hell!
But, a long long time ago, I sh@gged one sheep..."
