President Barack Obama gets a nice little salary. Certainly some CEOs, entrepreneurs and movie stars are earning millions (and in some cases billions) of dollars, so he's by no means the richest person on the planet with his $400,000 annual salary. And he gets some pretty sweet perks -- a fancy plane, an amazing chef and one of the most famous addresses in the world.

But if you stop to think about all his job entails, he's never really off the clock. Although he takes vacations, he can't completely clock out as long as he is in office. Regardless of where he is, the Secret Service is monitoring his every move and he must respond to any crisis that arises. The only other job that requires you to be on call 24 hours a day without fail is that of a parent, and no one's paying you to do that, unfortunately.

Obama's salary (not including his perks) was divided by the 8,765 hours in a year, to figure that he earns $45.63 per hour. Again, not too shabby, but considering what a president has to put up with -- constant danger, huge responsibilities, graying hair, people throwing shoes -- it's a tough gig.

Here are 10 jobs that, while important and demanding, probably don't have the same pressure as that of Obama's, and they pay more than he gets:
