Jimmy Fallon seized an opportunity — and Donald Trump’s famous coiffure — during the Republican presidential nominee’s visit to The Tonight Show on Thursday.

Toward the end of his conversation with Trump, a giddy Fallon asked, “Can I mess your hair up?” As Trump mugged for the cheering audience, Fallon promised, “I’ll be gentle.”

When the commotion subsided, Trump obliged: “The answer is yes, but the people in New Hampshire, where I’m going to be in about an hour from now, I hope they’re going to understand.”

Fallon fiercely tousled his guest’s hair, and then his own in a gesture of solidarity. Trump tried in vain to restore his bouffant as the show went to commercial.

Earlier in the segment, Fallon thanked Trump for providing him with a constant supply of comedic fodder by saying “some shocking things.”

“But I’m trying not to anymore,” Trump deadpanned.

Fallon previously touched the hair of Trump’s Democratic rival, Hillary Clinton, during an episode one year ago (almost to the day). She’ll return to The Tonight Show on Monday.

Watch the hair tussle below.
