(CNN) - Mitt Romney cracked wise about former President Bill Clinton Tuesday, seconds after the 42nd president introduced the Republican nominee at the Clinton Global Initiative in New York City.
"Thank you, Mr. President. I appreciate the kind words and your invitation here today. If there's one thing we've learned this election season, it's that a few words from Bill Clinton can do any man a lot of good," Romney said, drawing laughs.

His quip likely refers to a couple Clinton comments during this campaign year. On CNN's "Piers Morgan Tonight" in May, Clinton referred to Romney as having had a "sterling business career," a comment capitalized on by the Republican's campaign.
More often his words have been used to boost the current president. Clinton, a top surrogate for Obama, gave a widely-praised speech at the Democratic National Convention earlier this month, spending 48 minutes making the case for a second term for President Barack Obama.
In fact, more viewers of the DNC considered Clinton to be the highlight of the weeklong event, rather than Obama, according to a recent Pew Research Center poll. Some political analysts credited the president's mild post-convention bounce in the polls to Clinton's rousing speech.
Romney, however, poked fun at the Clinton factor while kicking off his foreign policy speech Tuesday.
"After that introduction, I guess all I have to do is wait a day or two for the bounce," Romney said, drawing laughs.
