Little Johnny's preschool class went on a field trip to the fire station. The fireman giving the presentation held up a smoke detector and asked: "Does anyone know what this is?"
Little Johnny's hand shot up and he said: "That's how Mommy knows supper is ready!"
Bob, a 70-year-old, extremely wealthy widower, showed up at the Country Club with a breathtakingly beautiful and very sexy 25-year-old blonde-haired woman who knocked everyone's socks off with her youthful sex appeal and charm and who hung over Bob's arm and listened intently to his every word.
His buddies at the club are all aghast. At the very first chance, they cornered him to ask, "Bob, how'd you get the trophy girlfriend?" Bob replied, "Girlfriend? She's my wife!"
They are now even more knocked out. So now they ask 'How the hell did you persuade that fox to marry you?" "I lied about my age," Bob replied. "What, did you tell her you were only 50?"
