Hillary Clinton got laughs when she took a "pot" shot at Colorado's marijuana laws during a campaign stop at a coffee shop.

During the former secretary of state's visit to Denver Monday, a barista at the Pigtrain Coffee shop made Clinton a latte with artwork drawn in to the foam, and boy did she get excited.

"Oh my god. Oh my god," Clinton said, summoning over Sen. Mark Udall, who she was campaigning for in the state. "Look at this. Look at this."

Atop Clinton's latte was an image of a smiling pig, named after the local coffee shop the two politicians stopped by, that Clinton said she liked too much to actually drink. But, it was Udall's latte, topped with one simple leaf, that really sent Clinton cracking.

"Look at you," she said to him in wonder as the barista handed the second beverage over. And then it clicked.

"Is that a marijuana plant?" she quipped with a wink, the room erupting in laughter.

"That's exactly what it is," the barista responded.

Clinton then took some selfies with locals and chatted with the crowd before heading off to Las Vegas for two fundraising events, one for Sen. Harry Reid and one for the University of Nevada, Las Vegas, where she delivered a keynote.
