Marlon Wayans

I'm the most inappropriate dad. I curse in front of my kids and their friends. I let my kids watch R-rated movies. I'll walk by the movie theater and say, 'Let's go see that,' and my kids will say, 'No, it's rated R. It's not appropriate for kids.' I'm like Uncle Dad. We have fun. I don't live with them, but I drive over four days a week.

If you think about evolution, sleep, at some time, was a dangerous undertaking. You lie down in your cave or shelter, and along comes a predator and has you for dinner. Many creatures do not sleep or sleep while standing so they can escape from dangerous situations.
