Since i dont tow, i never thought i needed balls, but i figured, i may as well buy some in case i do, i mean, i would'nt want to be caught in a situation where i needed balls but did'nt have them. So now i keep 2 different sizes handy, just in case. Now when people ask "Do you have any balls?" i can say, "Yes i do, would you like to see them?" and when i show them, i always get compliments, the last person said, "Wow, thats some set of balls you have". I only wish they got more use.
