5. Simon Cowell

Everyone’s favorite talent show bully has more than one unusual leisure activity that he enjoys. Perhaps as an effort to stay in touch with his inner child (one who bullied others at the playground no doubt!), Cowell likes to climb trees! It’s an activity Cowell reportedly engages in on a daily basis. In addition to the tree thing, he also enjoys watching old cartoons such as The Flintstones and The Jetsons. We can’t fault him for that, but we find that spending some quality tube time with Bugs Bunny or the Roadrunner is decidedly more intellectually stimulating.
