The two old coots were both only a year short of retirement from the assembly line, but one Monday morning that didn't keep Joe from
boasting to Manny about his sexual endurance.  "Three times," gasped Manny admiringly. "How'd you do it?"  "It was easy." Joe looked down modestly. "I made love to my wife, and then I rolled over and took a ten-minute nap. When I woke up again, I made love to her again and took another ten-minute nap. And then I put it to her again. Can you believe it! I woke up this morning feeling like a bull, I'll tell you."  "I gotta try it," said Manny. "Lorraine won't believe it's happening." So that night he made love to his wife, took a ten-minute nap, made love to her again, took another nap, woke up and made love to her a third time, then rolled over and fell sound asleep.  He woke up feeling like a million bucks, pulled on his clothes, and ran to the factory, where he found his boss waiting outside for him. "What's up, Boss?" he asked. "I've been working for you for twenty years and never been late once. You aren't going to hold these twenty minutes against me now, are you?"  "What twenty minutes?" growled the boss. "Where were you on Tuesday and Wednesday?"
