My balls created some sick momentum at the Newton's Cradle party last night but now my balls are sore. Are yours?

Get the Newton's Cradlemug. The Missouri Newton's Cradle is an activity in which 4 or more men tie a rope or string with a weight around their scrotum. They line up, generally close together and facing one direction, and the one in the front pulls their weight forward and releases it so it hits the weight behind his. This will go on to the last person and then you have completed the Missouri Newton's Cradle.
Have you seen Josh, he has been walking funny ever since he took 50 pounds at last night's Missouri Newton's Cradle.
