I think it was last night's anyway--sometimes I get confused since we DVR everything we watch. We got hooked on the show when we got a fast enough internet connection to watch Amazon Prime video and are caught up the the current season.
Anyway, one of the main characters, Ron Swanson is nominated for an award from the Indiana Fine Woodworking Association or something like that for a chair he built. He attends the banquet and right away see's Chris Becksvoort. They spend a fair bit of time, at least in TV terms, at the Lee Valley/Veritas booth. Then during the awards they announce the nominees including of course Ron, but also Asa Christiana (of Fine Woodworking). Ron of course wins the award and they show Christiana throwing down his napkin and rushing out in disgust. Both Becksvoort and Christiana play themselves in the show.
