From the groaners listserv.
In the late 1800s, not wanting to be outdone by American rodeo, an English chap decided to become a rodeo star. Not having a horse or any cattle, he cast about for some way to perform. His vocation was building outhouses, and he had several samples behind his home. He had also installed a couple of standing gas lamps in his yard. As a start, he decided that lassoing these objects would be good practice. After all, he reasoned, they may not be moving targets, but he could at least gain skill in controlling the rope.
Now he needed a mount. Not having a horse, he thought a bicycle would be a good substitute, and so he grabbed a coil of rope, hopped on his bicycle and off he went. He was phenomenally successful, and quickly got the hang of it. After the Englishman had been practicing for a couple of weeks, he could ride with no hands, twirling two lassoes at the same time. He proceeded to lasso an outhouse, then immediately followed with a perfect throw over one of the lamps, all the while singing, “Here we go loop the loo. Here we go loop the light!”
