Early in the debate, Harris referenced The Wizard of Oz while taking a dig at President Donald Trump. "The bottom line is this: Donald Trump, in office on trade policy, you know, he reminds me of that guy in The Wizard of Oz," she said. "You know, when you pull back the curtain, it's a really small dude?"

Although it was former Rep. Beto O'Rourke who first made waves by speaking Spanish at a presidential debate, Sen. Cory Booker jokingly sought to translate one of his answers from English into Spanish at the third Democratic debate. "First of all, I want to say, no," Booker said, when asked if he felt Americans should become vegans like himself. "Actually, I want to translate that into Spanish, 'No.'"

Any parent who has ever referenced or quoted a well-known pop culture moment only to find their kids, less than impressed, rolling their eyes, likely cringed out of embarrassment for Amy Klobuchar. According to The Hill, the Minnesota senator attempted to take a dig at Trump by accusing him of running the country "like a game show" after uttering an infamous line: "Houston, we have a problem." Clearly proud of her joke, Klobuchar attempted to continue the reference Friday with a tweet featuring a selfie in "the astronaut mirror in the Houston Marriott elevator."

Known for often poking fun at Asian stereotypes, Andrew Yang worked a joke about how Asians are often typecast into his plan for health care. "Now, I'm Asian so I know a lot of doctors," Yang said Thursday, before divulging some of the insights his doctor friends had shared with him about the current health care system's issues.

Not too far into the debate, Klobuchar hit viewers with a second joke, this time going for a Biblical reference. "Day four, five, and six, I'll work on sweeping legislation with Congress and local governments," The Hill reported she said while outlining her plan to tackle climate change during her first week in office. "And on day seven you're supposed to rest, but I won't." Her The Day After Tomorrow reference also shouldn't be overlooked.

Booker dropped another epic dad-esque joke Thursday when criticizing President Trump's decision to use a national security waiver to impose steel and aluminum tariffs on Canada in 2018. "Now look, I'm the only person on this stage who finds Trudeau's hair menacing but they are not a national security threat," Booker, who is bald, said.

While the important part of presidential debates aren't the jokes, a little humor never hurt. But be honest, would any of the Democratic presidential candidates' jokes make the cut with your kids?
