5th annual office pie fight.

Annual? this company does it every year?

In my dream world.yes.

They need to keep their large budget somehow... If they don't use the full budget, then corporate thinks they don't need such a large budget.

So the office improves their financial efficiency every year, just so they can use the increasing funds for a massive pie fight. Of course, a significant chunk of the end-of-the-year party's budget is spent on cleanup...

Yep
