A dm, center manager, and ds were standing at the end of the belt, watching the drivers load packages. As they stood there, they began a personal conversation about matters erotic. The dm said, "I think sex is 75% fun, and 25% work." The center manager countered, "I think sex is 50% work and 50% fun." The ds chimed in with, "I think sex is 25% work, and 75% fun." A driver working nearby stopped loading and said, "You're all wrong. Sex is 100% fun and I can prove it. If there was any work involved at all, you guys would find a way for me to do it for you!"
