Shooting the skit. Notice that there’s no one in the audience except Buffalo Guy and Buffalo Gal. I believe they shot a few takes this way to ensure good sound for when Brian and Marla say their lines.
Another angle of Buffalo Guy and Buffalo Gal watching the skit.
Shooting Andy welcoming everyone to the picnic.
A word about Andy Buckley: Andy is one amazingly entertaining guy. I believe the SlumDunder Mifflinaire scene took a few hours to shoot, and during the breaks, Andy had a captive audience (us extras in the crowd, who weren’t allowed to move from our spots), so he would regale us with stories from his past (including his stint in a college production of ‘Hair,’) tell jokes, and even sing! Awesome Blossom, extra awesome.
