The ugly and public outburst of long-running tensions between Dan Harmon and Chevy Chase peaked over the filming of "Digital Estate Planning", which was the final episode filmed for Season 3 due to the time needed to complete the extensive "1980 video game" special effects (although it was never intended to be the season finale and ended up airing as the 3rd-to-last show of the season). Dan Harmon said that he wrote a scene after the story's resolution where Abed handed Pierce Hawthorne a floppy disk to use, and Pierce was left in tears when he saw it was a computer simulation of Pierce's late, horrible father having a game of catch with his son. But Chevy Chase was tired of the delays in the shooting schedule and left the set after his final scripted scene was done, even as Harmon tried to explain this extra scene and begged him to stay and film it. Harmon later said he was so angry over Chase's actions that he over-reacted and this led to their problems becoming embarrassingly public.
The legal agreement that Gilbert has to digitally agree to in order to receive Pierce's fathers inheritance is actually Article I, section 2 of the US Constitution, better known as the 3/5th Compromise.
After Abed has maxed out Hilda's trust and affection, some of the show related actions she can perform in the front-end scripting language are "Kickpunch(er)" and "(Inspector) Spacetime RPG."
