Post Malone and Jimmy Fallon seem to have the best time together, and I need to make my way into these hangouts.

Last time Post Malone visited 'The Tonight Show' he showed Jimmy around the Olive Garden, his favorite restaurant.

This time around, the two had even more fun. They performed a duet of 'Seven Drunken Nights,' and had the audience cracking up.

After their beautiful rendition of 'Seven Drunken Nights,' Jimmy wanted to know the behind the scenes of what happens when Posty is on tour.

Post Malone explained to Jimmy just how important the Cheetos and Bud Lights were, and he always has a game of beer pong going with Shania Twain playing in the background.

How do any of us get in on this bro-mance?!
