This joke is funny because "cup" (a sporting contest in which a cup/trophy is awarded) is phonetically similar to "cup" (a protective reinforcement of rigid plastic inserted into jockstrap to protect the delicate hanging spherical bits of the male reproductive organ). #WorldCup https://t.co/PkDrprUGZc https://t.co/aJbQ1zUXIJ
