It is believed to have originated from London where tennis was very popular back in the 1920s. A lot of services were fumbled and the two service rule came into being. Now, a lot of women also have two balls.
WTF???? You guys are ruinning a very interesting thread. I'm very disapointed by that attitude. I'm going to ban someone who's not a member to show you my power. You've heard of mods banning members but banning non-members? HA. Be scared. Be very scared.
Dude you left yourself wide open for all sorts of craziness with that title. Be thankful this thread hasn't collapsed under the weight off its own ridiculousness, cause it has that potential. Don't take these RT posters lightly. Now make amends.
Well, it started poorly but it did get better. To answer the eternal old question about why not two dicks instead of two balls - you need two balls to power one dick. It's like a flashlight - many batteries but only one light. If you'd have two lights for one battery - it wouldn't shine so much. Same with balls & dicks. If you have too many dicks working the power of one ball - your hard-on won't be as long or strong. Hope these technical specs help.
