Sen. Elizabeth Warren (D-Mass.) stopped by the “Tonight Show With Jimmy Fallon” on Tuesday to plug her new book, but she also shared a few pointers on how Democrats should approach the next few years — including a Pixar-inspired analogy.

“We cannot shoot at everything that moves,” she told Fallon. “Remember in the movie ‘Up,’ the dog, when he yells, ‘Squirrel!’? We cannot all go over there.”

She added: “We got to keep a focus not on what says, what he tweets. We got to keep the focus on what he actually does.”

But to Warren, Trump’s nearly 100 days in office “feels like dog years, he’s been there forever.”

Fallon told Warren he “heard Mitch McConnell won’t make eye contact with you,” before eventually addressing the Republican leader directly: “Mitch McConnell, you have to say hi to Elizabeth Warren,” he said. “How old are we now? This is silly.”

Earlier this month, Warren hinted that she has gotten the cold shoulder from the Republican majority leader ever since her viral moment in February when Republicans formally rebuked her during the attorney general nomination debate. McConnell cut Warren’s floor speech short and said, “She was warned. She was given an explanation. Nevertheless, she persisted” —  a phrase that has quickly became a rallying cry among her sympathizers, spawned tons of positive media coverage and even inspired some to get “nevertheless, she persisted” tattoos.

“I’ve spoken to him, but he has not spoken to me,” Warren told the Boston Globe this month. “I say hello to Mitch every chance I get, and he turns his head.”

Fallon, who has been competing with CBS’s Stephen Colbert in a late-night ratings war, is perceived as much softer on politics, particularly when it comes to Trump — symbolized by that Trump hair-tousle. Colbert offers much sharper anti-Trump takedowns, and his ratings have risen since Trump’s election. He beat out Fallon in a nine-week streak.

The hair-tousle analysis is one Colbert himself tried to tamp down in a recent New York Times profile. “The theory that that hair tousle made a difference is based on the supposition that Jimmy’s fans went to him for political acumen,” Colbert said. “I don’t think so. They go there for fun. They go there for his nature, his spirit.”
