Each Friday night I drove my wife to the train station so she could go visit her sister who was ill. Ten minutes later, MY sister arrived by train so that she could manage our house over the weekend while my wife was gone. On Sundays this procedure worked in reverse with my sister departing by train ten minutes before my wife arrived.

One evening after my sister left and while I awaited my wife's arrival, a porter sauntered over.

"Mister," he said, "you sure have some system going! But one of these days you're goin' to get caught!"

 "At the gym, a guy asked me to "spot" for him while he did the bench press. What did he mean? "Spotting" for someone means you stand over him while he blows air up your shorts. It's an accepted practice at health clubs; though if you find that it becomes the ONLY reason why you're going in, you probably ought to reevaluate your exercise program."
