Clearly, Fallon captured Trump's overwhelming confidence, especially in light of winning seven states during the election's biggest primary day.
Everything is coming up roses for Trump, even if they really aren't.
"Now, I'll admit I didn't win every state. I only got 27% of the vote in Texas. But remember, everything is bigger in Texas. So 27% is more like 60%, so basically I won Texas," Fallon's Trump says.
He then dismisses a cardboard cutout of recent endorser Chris Christie, whose sad demeanor while standing behind Trump during his Super Tuesday speech didn't go unnoticed by the internet.
"Of course, I want to thank Governor Chris Christie for his unblinking support," Fallon's Trump said, pointing to the cutout. "He's like my mini-me, except bigger. He's my mega-me."

Going into Super Tuesday, Trump was embroiled in controversy over failing to disavow supporters from white-supremacist groups, including KKK leader David Duke. Fallon adds a twist in his sketch.
"Look, first of all, I love the KKK: Kim, Khloe, Kourtney," he refers to the Kardashian sisters. "They're fantastic people. I've known them a long time."
And what about David Duke? Fallon captures Trump's talent for bending the truth.
"As for David Duke, I've already disavowed that. I disavowed that like five times. But, everyone is still, 'Damn, Donald, back at it again with the white supremacists.' Next question."
And as for how the Republican presidential candidate would handle support from the Nazi party?
"Look, I support people who can not see."
After dismissing Marco Rubio's refusal to drop out of the race, Fallon's Trump explains that his real competition at this point is Hillary Clinton. In fact, he has a very clear message for her.
"I called Hillary earlier. I said, 'Here's the deal. In 2008, you lost to a black man. But in 2016, you're going to lose to an orange man.' That's right: Orange is the new black," he joked.
