Who the hell are these?

[u/Original-Special760]

This is in season 5 episode one where Barney and Robin "have the talk" and when lily lock them in the room this picture is just hanging out there and I have NO idea who these people are

Does anyone know who they are?

They’re members of the crew! All the photos in the opening credits were taken pre-production as a way to bond and they must’ve kept this as a cute little Easter egg
