Remember the time Martin O'Malley almost quoted Donald Trump, Bernie Sanders joked about his weight, and Hillary Clinton picked Abraham Lincoln over Barack and Bill? It all happened at the Democratic Party's town hall meeting in Iowa on Monday.

Announced just last week, the event provided the three Democratic contenders in the race for the White House one last chance to appeal to Iowa voters on national television before they head to the caucus February 1. Each candidate was given 30 minutes of air time, fielding questions from the audience and from moderator and CNN host Chris Cuomo.

While the format lacked the back-and-forth of debate, it gave viewers perhaps a more candid look at each of the candidates and fostered a more personalized tone. Who knew Sanders was an elementary school basketball champion?

Even though the candidates didn't face off directly on stage, they were hyper aware of one another's presence. Sanders came perhaps especially prepared to attack rival Clinton. The former secretary of state, on the other hand, appeared more careful in her approach to the Vermont senator -- she knows she will need his supporters if and when she makes it to the general election.

This is the last time the Dems will appear together in an official event before primary voting begins. In case you didn't catch last night's event, here are three big moments you won't want to miss.

1. Hillary Wants Bear Hugs with the GOP

At the October presidential debate, Clinton said Republicans were the enemy she's most proud of. Now, it looks like she wants to kiss and make up -- or bear hug, rather.

When asked by Cuomo about her contentious relationship with the GOP, the former first lady said that when she is in office, "they say really nice things about me." The problem, she explained, is when she is in a race. "When I run, oh my goodness, it's just unbelievable," she said.

But Clinton remains hopeful that once in the Oval Office, she can find common ground and build bridges with her political foes.

"It takes building relationships, and that is one of the hardest things to do in politics over ideological and partisan lines," she said. "So, I'm just going to be giving them all bear hugs whether they like it or not."

She'll even be embracing those behind the Benghazi hearings. "It would be very gracious of me to go back and talk to them," she said.

2. O'Malley Takes Off His Jacket

Still failing to make a real dent in the polls, O'Malley has next-to-nothing left to lose in his 2016 bid for the White House. And on Monday, it showed.

When asked by Cuomo how he is feeling a week ahead of the Iowa caucus, he said he is excited and still holds out hope for success. "Once Iowans get into that decision-making pocket, none of the pollsters back East can tell you how it's going to turn out," he said. He later added, "I'm in this ... to win this," when asked about The Des Moines Register's suggestion he would be better suited for a position in the White House cabinet than for the presidency.

He really got rolling when Q&A time started. As the first question was being asked -- regarding contrasts between his tough-on-crime record as mayor and governor with his current platform to fight structural racism -- O'Malley stood up, took off his jacket, and rolled up his sleeves.

He went on to field questions about the farming industry, LGBT rights and bringing unemployed and underemployed Americans back into the workforce.

And when asked by Cuomo near the close of his time who he hopes his supporters will follow in the event that he doesn't meet the 15% viability threshold, O'Malley again pushed back against the idea that his campaign was over. "My message to the O'Malley supporters across the state is this: hold strong to your caucus," he said.

3. Sanders Makes His Closing Argument

One year ago, Sanders was some socialist senator from Vermont who was promising not to run for the White House as an independent as Dems hoped for another progressive, Elizabeth Warren, to throw her hat into the ring instead. Today, he is giving once-presumptive nominee Clinton a run for her money.

On Monday, even Sanders expressed astonishment at his political ascent. "Our message has resonated much faster, much further than I thought it would," he said.

Senator Sanders came equipped to lay out his own case as well as to draw contrasts between himself and frontrunner Clinton. He highlighted their differences on issues like the Iraq War, the Trans-Pacific Partnership and the Keystone Pipeline (he opposed them all from the get-go, she didn't). His message: Clinton's resume doesn't necessarily translate to superiority.

"Experience is important, but judgment is also important," he said.

He also took advantage of his 30-minute slot to address his age. Now 74 years old, Sanders would be the oldest person elected to the presidency. When Cuomo prodded him about the issue, the senator responded with humor. "I'm going on 75, so are you! You're going to be 75 someday," he said, to laughter.
