Following a tradition that dates back to 1920, President Barack Obama took to the podium at the White House Correspondents' Dinner last weekend and let the jokes fly. 


“It’s nice to be here in the nice, vast Hilton ballroom. Or as Mitt Romney would call it, a fixer-upper,” Obama quipped to the more than 2,000 journalists, celebrities and politicians in attendance. 


The annual dinner is an opportunity for both the president and the journalism community to enjoy a bit of comedy and honor the achievements of news makers. 


In one segment, Obama also made fun of right-wing claims that he’s fond of eating dogs. ”What’s the difference between a hockey mom and a pitbull?” the president asked, using Sarah Palin’s favorite line. “A pitbull is delicious!”


Continuing on that theme, Obama took the opportunity to mock likely GOP presidential nominee Mitt Romney about his famous “dog-on-roof” incident. Back in 1983, on a Romney family trip from Boston to Ontario, Mitt placed the family dog, Seamus, in a pet carrier strapped to the roof of the car. He has received scorn from animal rights activists ever since.


On Saturday, the president’s team created a mock attack ad praising Romney for allowing his dog to “feel the wind in his fur” while Obama keeps Bo shuttered behind "socialist" pet policies. 


“America’s dogs can’t afford four more years of Obama,” the spoof says. “For them, that’s almost 28 years.”


Take a look at the spoof ad below.
