Onions and Christmas Trees

A couple with a son and a daughter was having a meal together. At a certain point, the son decides to ask the father: “Dad, how many types of boobs are there?” “Three.” “How so?” “When you’re 20, they’re like melons: gorgeous and round. When you’re 40, they’re like pears: they are dropping, but still look pretty. When you’re 60, they’re like onions.” “Onions?” “When you look at them, you just want to cry!” The daughter overhears the conversation and asks the mother: “Mom, how many types of penis are there?” “Three.” “How so?” “When you’re 20, it’s like a sequoia: tough and long. When you’re 40, it’s like a willow: it starts to lose its strength, but it’s still respectable. When you’re 60, it’s like a Christmas tree.” “A Christmas tree?” “It’s dead from the root to the tip, the balls serve as a mere decoration, and the worst part is that it’s only active once a year!”
