Explaining Poo

A little boy asks his dad "Where does poo come from?" His father is taken aback by the question but decides to give his son the facts straight up.
"Well son," he says, "food passes down the esophagus by peristalsis. It enters the stomach, where digestive enzymes induce a probiotic reaction in the alimentary canal. This contracts the protein before waste enters the colon. Water is absorbed, whereupon it enters the rectum finally to emerge as poo."
"Wow," says the boy. "So where does Tigger come from?"

Evolution

A child asked his father, "How were people born?" So his father said, "Adam and Eve made babies, then their babies became adults and made babies, and so on." The child then went to his mother, asked her the same question and she told him, "We share a common ancestor with monkeys and we evolved to become like we are now." The child ran back to his father and said, "You lied to me!" His father replied, "No, your mom was talking about her side of the family."

Gunpoint

A terrorist was holding a dad at gunpoint:
Terrorist: "Say your last words!"
Dad: "Your last words!"
Terrorist: "What? ugh, you Americans. Be serious!"
Dad: "Okay, I'll be Sirius. Who are you going to be?"
Terrorist: "Stop. Why isn't this scaring your?"
Dad: "Nothing really scares me anymore; not since I saw that monster henway."
Terrorist: "What's a 'henway'"?
Dad: "About a pound and a half."
Terrorist: "Stop! I'm serious!"
Dad: "Hi Sirius! I'm Dad!"
