I recall an old joke where a foreman was trying to impress a lady with his signing skills on a job site. He waved his arms to a distant worker, and when he got his attention, the foreman pointed to his eye, then to his knee, then back to the guy. The person responded by making masturbatory gestures. Furious, the foreman walked over to the guy and yelled, "What in hell were you doing? I was telling you that I needed you!" The guy replied, "Yeah, I know! I was telling you that I'm coming!"
