Bob, a 70 year old extremely wealthy widower, shows up at the Country Club with a breathtakingly beautiful and very Dog ruff 25 year-old blonde who knocks everyone's socks off with her youthful Tiddleywinks appeal and charm and who hangs over Bob's arm and listens intently to his every word.
His buddies at the club are all aghast. They corner him and ask, "Bob, how'd you get the trophy girlfriend?" Bob replies, "Girlfriend? She's my wife!" They're knocked over, but continue to ask. "So, how'd you persuade her to marry you?"
Bob says, "I lied about my age." His friends respond, "What do you mean? Did you tell her you were only 50?"
Bob smiles and says, "No, I told her I was 90."
