It has been nearly six years since the last episode of "The Office" aired, and still its stars have a special bond.

Jenna Fischer (Pam) was a guest on Busy Philipps's late-night talk show, "Busy Tonight," on Tuesday, so the host called on Fischer's former co-stars to send early birthday presents for her to open on camera. Fischer seemed to love them all, but it was a gift from Steve Carell (Michael) that brought her to tears. He really nailed it, as you'll see below.

As touching (yet also scary) as Carell's surprise was, we're impressed with the others as well. "The Office" cast clearly bonded during their years together, much like their Dunder Mifflin counterparts did. It's not surprising that there's always talk about them reuniting for an "Office" revival. We could see it happening someday.

New episodes of "Busy Tonight" air Monday through Thursday at 11 p.m. ET/PT on E!.
