With less than three months to go until the US presidential election, what better time for president Obama to remind voters about the time Mitt Romney strapped his dog to the top of his car.
In a speech on renewable energy on Tuesday, Obama took aim at Romney's energy policies and reminded voters about the Republican candidate's approach to animal welfare.
"Governor Romney even explained his energy policy this way, I'm quoting here, 'you can't drive a car with a windmill on it'," Obama said.
"I don't know if he's actually tried that," he added with a smile. "I know he's had other things on his car."
Obama's joke was a reference to the infamous incident in the early 1980s when Romney strapped his dog Seamus to the roof of his car as his family drove from Boston to Ontario.
Although Romney has defended his actions, claiming Seameus enjoyed the ride, he did have to pull over to the side of the road at one point on the 12-hour drive to wash dog diarrhea off the windscreen.
Responding to the jibe, the Romney campaign said Obama "continues to embarrass himself and diminish his office with his un-presidential behaviour".
“This election is about creating jobs, turning around our economy and helping the middle class. The President’s policies have failed on all counts and he will do anything to distract from his abysmal record."
Reince Priebus, the chairman of the Republican National Committee, tweeted: "Obama campaign about small things - accusing Romney of being a felon & murderer. Next thing you know, they'll accuse Romney of eating a dog."
Searching around for a way to hit back at frequent jokes about Romney's dog, the Republican's campaign have in the past pointed to a passage in Obama's book, 'Dreams of My Father', in which he recounts the time he ate dog as a child.
"Away from the dinner table I was introduced to dog meat, (tough), snake meat (tougher), and roasted grass hoppers, (crunchy)," Obama recalls.
Obama's campaign chief, David Axelrod, has also made a few light hearted references to Romney's dog problems on his Twitter feed.
In May he said: "Pack up the dog, we're headed to Florida, where the palm trees, taxes and electoral votes are all the right height!"
And in January he tweeted a picture of Obama in a car with his dog Bo: "How loving owners transport their dogs."
After discovering the passage in Obama's book that revealed the dog dinner, senior Romney adviser Eric Fehrnstrom hit back:
