Obama Says He Will Walk John Boehner's Nonexistent Dog

The president has been using the same joke about compromise since 2012.

The president has been offering to wash his detractors' cars and walk their dogs for more than two years.

President Obama, in trying to push for compromise on immigration legislation with Republicans, included a favorite joke during a speech on Friday at a Las Vegas high school, where he first outlined his plans for reform two years ago.

"I told John Boehner, you know, I'll wash your car. I'll walk your dog, whatever you need to do," Obama said, referring to last summer, when a bipartisan immigration bill had passed in the Senate, but the House speaker refused to call a vote in his chamber.

Thing is, Boehner doesn't have a dog, his office tells National Journal.

The president offered his car-washing and dog-walking services in Ohio in September 2012, in exchange for compromise with Republicans to reduce the deficit, via CNS News:

While speaking in Cincinnati on Monday, Obama said, "The only thing they [Republicans] can do is keep trying to bluff their way through until November, and hope that you won't call them on it. But understand Cincinnati, look, I want to work with them to reduce the deficit. I've said if the Republicans need more love, if they want me to walk the dog or wash their car, I'm happy to do it."

And on the radio in October 2012, on working with Republican leaders to reach a bipartisan deficit- and debt-reduction deal, via Politico:

"I'll wash John Boehner's car, I'll walk Mitch McConnell's dog," Obama said in a Friday interview with radio host Michael Smerconish, referring respective [sic.] to the House Speaker and Senate minority leader.

And at the White House in July, about equal pay and labor legislation, via Bloomberg:

"I'll go to them," he said of Congress. "I'll wash their car, walk their dog."
