Every group of friends has the unofficial leader--or 'The Catalyst.' Sure, the Legion of Dudes has more egos than the usual friend group, but it's still the leader's role to always keep his high-status amigos out of trouble, and in the party.

But what makes a good catalyst? Is it good looks? Sure, couldn't hurt. Irresistible charm? Why not. And how about the ability to get whatever you want, when you want it with just the blink of an eye or the shake of a hand? Yeah, that sounds about right.

Yes, being The Catalyst of the Legion of Dudes is no easy feat, but one the following ten celebrity contestants will most indubitably be up for the task.

  • Alec Baldwin

    The best types of leaders are imperfect. Baldwin has overcome alcoholism and a contentious divorce with ex-wife Kim Basinger to become one of the most respected film and television actors in the business. Suffice to say, most would follow Jack Donaghy into battle.

  • Bradley Cooper

    Cooper played a convincing friend group leader in now-series 'The Hangover'. The actor's roll as the ever-charismatic Phil perhaps epitomizes the type of leader the Legion of Dude would need. Plus, if you ever found a tiger in your bathroom, Bradley Cooper would know how to bail you out.

  • Neil Patrick Harris

    Neil Patrick Harris has starred as two of the most beloved television characters in history: Dr. Doogie Howser and Barney Stinson. Plus, the guy can sing and dance. Is there a role NPH couldn't play? Even if he isn't really Barney Stinson, he could at least pass off some wisdom about passing yourself off as Barney Stinson.

  • Jay-Z

    Jay-Z is quickly becoming one of the most successful, and diverse businessmen in history. The rapper got his start in music, and reigned as the CEO of Def Jam Recordings for years. Jay-Z now spends his time as founder of Rocawear, part-owner of the Brooklyn Nets, and husband to the incredibly sexy and talented Beyonce. His track record speaks for itself.

  • Derek Jeter

    Over the past eighteen years, Derek Jeter has helped lead the New York Yankees to a whopping five World Series wins. His personal achievements are equally as impressive, including thirteen All-Star games, well over 3,000 hits, and even has more hits than any other Yankee in history. Jeter is also quite the ladies man, having dated the likes of Mariah Carey, Jessica Biel, and Minka Kelly. Yeah, Derek Jeter knows the score.

  • Jon Hamm

    Jon Hamm has become the definition of cool. As Don Draper in the cult AMC series Mad Men, Hamm is able to woo any woman, and seemingly drink crates of scotch. As if his fictional Draper character wasn't cool enough, apparently Hamm has the full package in real life too.

  • George Clooney

    There might not be a consistently cooler, more suave Hollywood actor than George Clooney. Clooney has won two Academy Awards, is always involved in the most pressing global charities, and refuses to let go of his precious single-hood. Plus, the guy had a pet pig for nineteeen years!

  • Idris Elba

    The first rule for any Legion of Dude member is to be familiar with the television series The Wire. It's a must. So who better to lead than Idris Elba--the man behind Russell "Stringer" Bell. Also, Elba is rumored to be the next-in-line for the James Bond series once Daniel Craig is done. Could there be two cooler roles than Stringer and Bond? (Answer: no).

  • Mark Cuban

    Mostly known as the outspoken owner of the NBA franchise Dallas Mavericks, Cuban got his start in the tech world, taking a small business he co-founded with a college friend, and spinning it into a $5.9 billion Yahoo acquisition.

    Cuban is also responsible for leading the Mavericks out of the gutter, and into a perennial playoff contender. The boisterous owner might get fined a lot, but you got to respect someone who speaks up for what he believes in, and puts his money where his mouth is.

  • Bill Clinton

    When Clinton left the White House in 2001, his 66% Gallup poll approval rating was the second highest in history. But unlike George Bush, who faded into oblivion once retired from the presidency, Clinton has embraced his new role as the Democratic Party ambassador. The former President played a pivotal role in current President Barack Obama's re-election campaign. Without a doubt, Bill Clinton is a boss.
