Ballzheimers Disease strikes many men in their late seventies and early eighties. Medical experts agree a long history of deviant sexual behaviour as well as drinking chemical beer contribute to this disorder, in which the affected men; forget where their balls are, forget they have balls, or begin to play with their balls incessantly forgetting all else.
Barry, fond of telling his favourite stories of barnyard sex, experienced a sudden onset of Ballzheimers disease right after his 81st birthday. Barry forgot his history of having sex with poultry, and began to watch "Oprah" and reruns of "Little house on the Prairie".
Barry forgot all about constantly fondling his balls while he talked, forgot all about sex in general, and soon was completely overtaken by the disease.
