Once upon a time I met this cable. On one end it had a plug wiith a metal jacket and three pins arranged in a triangle. His name was Fred he told me, Fred XLR. On the other side was another plug, she introduced herself as Elsie XLR. Fred explained that Elsie and him had been married, and forever soldered together, by cable. He further went to explain that the ceremony had been undertaken by monsters somewhere in China, far away.
My first impressions of the XLR family were twofold. In the first place it was immediately apparent the they had an easy flow between them. Second, I was jealous of the three pins and three holes, which made me wonder if the XLR's also experienced three simultanious orgasms.
After sitting down with the XLR's, they continued to tell me their livestory. From their manufacture by the monsters, their trip on a big container vessel to the USA, their experiences while hanging on the wall at the Guitarcenter in Hollywood, and their subsequent removal, sale to a guy names Tommy Lee Jones, who took the XLR's home with him in his raincoat pocket...........
Is that sort off along the lines your teacher had in mind??
