The shirtless men, who arrived at the venue at 5 a.m. to secure their spots, were fully clothed when the event started but dramatically took them off as Clinton spoke.
The cops at the rally were going to ask them to leave, but Clinton joked that they could stay as long as they didn't take anything else off.
"I got to admit, it is a little distracting standing up here looking at [them]," Clinton said. "So I'm going to look over this way."
The two men are Dan Stifler and John Nelson — both 32 years old and both undecided voters who traveled to California to see all the candidates.
They don't like Trump, but they weren't totally sold on Clinton ... until today.
"She's the least bad candidate there is," Nelson, a West Palm Beach native, told ABC News. "We decided ... if you're going to go for somebody, you should go 100 percent. 'Cause it could be the other guy, and that's a million times worse."
"That other guy has other people who are always going 100 percent," said Stifler, who's from Grand Junction, Colorado.
When they finally met her on the rope line, Clinton laughed and said, "OK, guys!" and took a photo with them. As she walked away, Nelson grabbed a selfie video with her behind them.
"Finally found a candidate to settle for. We're going to settle for Hillary Clinton," Nelson said.
"That's right," Stifler said. "We're doing it!"
