We don't need to know why, when, or how this photo came to be—all we need to know is that it exists, and it's perfect.
As a bonus, though, we actually do know why, when, and how this photo came to be: Tom Hanks and Wiz Khalifa both appeared on Jimmy Kimmel Live! earlier this week when they took Christmas card photos with audience members, and this pic was snapped backstage. According to Wiz Khalifa himself on Instagram: "Toms hella chill. Hella."
They are probably best friends now.
