WGN anchor loses it over ‘that’s what she said’ joke mash-up from ‘The Office’

The WGN Morning News went off the rails -- again -- this time thanks to a mash-up of "that's what she said" jokes from the hilarious television show "The Office."

Anchor Larry Potash was in tears after the mash-up aired during the 9 a.m. newscast. It's unclear exactly what joke did him in, but he couldn't stop cracking up during Paul Konrad's weather forecast. He was still laughing as the team went to commercial break -- and it didn't help that Mike Toomey made one more "that's what she said" joke in his tease to upcoming segments in the newscast.

Check out the chaos unfold in the player above.
