Extra Tips and modifications for your ball and chain:
-----> you can paste a picture of the actual future spouse to the ball
-----> you can paste a picture on the ball of someone the bachelor/bachelorette really doesn't like
-----> you can draw some lame smiley face on the ball
-----> you can fill the other two finger holes with vaseline or something so the ball is not easily carried, and those holes are unpleasant to touch
-----> get a pink ball for your male friend
-----> get a black ball and put a BIG 8 on it
-----> you can make an actual padded cuff for the leg attachement out of carpet foam or pipe insulation
-----> you can make this ball a reusable item. have the bachelor/ bachelorette sign their spouses name. there's supposedly balls out there with over 100 names on them
-----> you could mail the key to the bachelor/bachelorette. maybe fed ex so they aren't tied up too long. or you could give the key to the future spouse to unlock the victim the next day...
