"I'd like to remind Stacey and Oprah and Will Ferrell, I'm kind of a big deal, too", Pence said, in an apparent reference to a line from Ferrell's hit 2004 film, "Anchorman".
Kemp is a staunch conservative who has embraced U.S. President Donald Trump and the administration's hard-line on immigration.
Pence was campaigning for Abrams' Republican opponent, Brian Kemp.
"It's my very first time ever canvassing for anybody, and it has been a really interesting experience because when you knock on a door, you don't know what people are going to do or say or how they're going to react", she said.

McDowell said Thursday that Winfrey's campaign efforts on behalf of Abrams is "going to get that woman elected".
On Sunday, President Trump is rallying for Kemp.
When a woman opens the door, she lets out an excited cry. Abrams' campaign has attracted support former President Barack Obama, who is rallying in the state on Friday.
More than 1.5 million of the state's nearly 7 million registered voters have cast ballots already. She recalled generations of black Americans who faced "lynching ... oppression ... suppression", and declared that "their blood has seeped into my DNA" and forced her to the polls. They don't help. Just ask Hillary Clinton. She's so passionate about her candidacy that she's made a decision to go door to door to canvassing for Abrams.
Ms Winfrey called Ms Abrams a "changemaker" who represented the values of all Georgians, where Atlanta is the capital city.
Georgia must make it easier for voters flagged as potential noncitizens to prove their US citizenship at the polls, a federal judge ruled Friday in an injunction ordering the state to change its procedure just four days before Election Day.
After Winfrey's speech, Abrams climbed the stage to join a discussion and was greeted by chants from the audience.
