Third-quarter Projection Analysis Spreadsheets
From Homestar Runner Wiki
Third-quarter projection analysis spreadsheets are what Strong Bad is often seen working on, when at The Office. Homestar apparently also worked on them, as seen in Biz Cas Fri 1. However, it is unknown if his were actually completed or started at all. Homestar's attempts to "help" Strong Bad on his caused a Flamboyant System Error.
In Biz Cas Fri 3, after Strong Bad's computer explodes, he claims he can see some of the third-quarter projection analysis spreadsheets in the burnt remains of the computer, and proceeds to "back them up".
