Actor, comedian and author Denis Leary

With his profanity-laden "guy's guy" humor and outrageously raw book Why We Suck: A Feel Good Guide to Staying Fat, Loud, Lazy and Stupid, actor and comedian Denis Leary may not seem like your typical Oprah fan...but he is one!

While writing his book, Denis—who also stars in the FX network series Rescue Me—says he wanted to include a chapter making fun of Oprah from a guy's point of view. "Truthfully, my mom loves you," Denis says. "My sisters, my mom, all my Irish aunts—they literally talk about you like you're at the house. They go, 'Well, Oprah said...' 'Well, Oprah thinks we should be doing this.' What, does Oprah call you? Me and my brother got sick of hearing it."

When Denis started researching Oprah, he says he turned to the Internet. "I Googled, and I got I'm a 50-year-old man, and I act like a 15-year-old boy on the Internet," he says. "I [searched] the word 'penis,' and there was an episode where Dr. Oz talked about how you can break your penis! ... What upset me is that I watch SportsCenter all the time, and no one mentioned a broken penis to me in my entire life!"

After a few more searches for things like prostate cancer and rip-claw hammers, Denis' mind had been made up. He changed the chapter that was going to make fun of Oprah to one that praises her instead. "If you had a crawl across the bottom of your TV screen that had the scores," Denis says, "every man in America would stop watching SportsCenter."
