Jimmy Fallon
and Justin Timberlake are the world’s greatest BFFs – and they know it.

After spending a whirlwind 24 hours together last week rapping, gushing about fatherhood and dancing to “Single Ladies,” the BFFs reunited on Monday’s Tonight Show for a hilarious new short celebrating their epic friendship.

“Do you ever have a friend that you get along with, that you can basically have a conversation without ever saying anything?” Fallon preceded the bit, titled “Looks.” “You just give them a look and you know what they’re thinking? Well, I have a friend like that and he stopped by the office earlier today.”

Set to the cheesiest rom-com music ever – the dreamy “Eyes” by Rogue Wave – Jimmy and Justin have an entire wordless conversation that would make anyone else in the room feel like a third wheel.
