Colbert, who plays a satirically conservative pundit, had criticized Clinton for the sheer number of celebrities and political figures featured in the pages of her book, which chronicles her time as secretary of State.

The comedian bragged he spent time with celebrities, too, noting that he had met actor George Clooney.

“Oh, I love George,” Clinton shot back. “I wish you could have joined us when we had lunch with Meryl Streep and Ecuadorian president Rafael Correa.”

Colbert shot back that he had gone camping with fellow television personality Oprah Winfrey.

“Oh?” Clinton responded.

“Oh, does that surprise you?” Colbert retorted.

“No, ‘O’ is just what all her real friends call Oprah,” the former first lady responded.

Clinton, laughing throughout the spot, was also able to match Colbert’s trump card — having taped a full episode of his show with President Clinton.

"I hate to break this two you Stephen, but I've met him too," Clinton joked of her husband.

The segment — which saw Clinton field questions about if she would rather fight a horse-sized duck or 100 duck-sized horses — was a rare moment of levity for the former first lady, widely considered the front runner for the Democratic presidential nomination in 2016.

When she appeared earlier this summer on "The Daily Show," which precedes Colbert on Comedy Central, host Jon Stewart pressed her on a possible run.

“I think I speak for everybody when I say nobody cares they just want to know if you are running for president,” Stewart joked.

During that appearance, Clinton did joke she preferred a “home office” and preferably one with “fewer corners.”
