(CNN) Jennifer Aniston and Brad Pitt shared a few laughs and showed common courtesy at the SAG Awards. Now there are calls for the friendly exes to reunite.

This is why we can't have nice things.

It started during the show, particularly as Pitt accepted his award for outstanding performance by a male actor in a supporting role for "Once Upon a Time... in Hollywood."

"Let's be honest, it was a difficult part," Pitt joked . "The guy who gets high, takes his shirt off, and doesn't get on with his wife. It's a big stretch. Big."

The camera then cut to a shot of Aniston, who clapped at the quip.
