A guy is jogging through the park, when he comes upon an old man, sitting on a park bench, sobbing uncontrollably.
"What's wrong, oldtimer?"
"I'm 84, and I'm married to a 26-year-old supermodel. She adores me. She cooks, cleans house, and we make wild, passionate love every night."
"Well, then, why are you crying?"
"I can't remember where I live!"
