(CNN) -- Barack Obama would make a great stand-up comic, not because he's the funniest president ever but because he uses jokes the same way many of us comedians do: As a weapon.
Traditionally, the (intentionally) funny lines by our presidents have had one thing in common: They were self-deprecating. Sure, some presidents have used jokes to take jabs at their opponents, but not to the extent of Obama.
During his tenure, he has increasingly unleashed biting comedic barbs against his critics and political adversaries. These jokes are intended to do more than simply entertain you. They have an agenda.
Obama's humor is often delivered the way a comedian dealing with a heckler would do it. He tries to undermine his opponents with it and get the crowd -- in this case the public -- on his side. I can assure you that having a crowd laugh at your critic/heckler is not only effective in dominating them, it's also very satisfying.
Let's look at some of the more typical self-deprecating jokes made by presidents at past White House Correspondents' Dinners, where press and president unleash their biting wits on one another. In 1988, Ronald Reagan joked about his advanced age by commenting that his staff had claimed that "preparing me for a press conference was like reinventing the wheel. Not true. I was around when the wheel was invented, and it was easier.
President Clinton, at the 2000 Correspondents' Dinner, mentioned that he was a fan of that night's comedian, Jay Leno: "Because, together, we give hope to gray-haired, chunky baby boomers everywhere."
