Unseen Academicals by Terry Pratchett (Discworld 37)

“Be one of the crowd? It went against everything a wizard stood for, and a wizard would not stand for anything if he could sit down for it, but even sitting down, you had to stand out.”

Returning to Unseen University for book thirty-seven, we find out that they need to field a football (soccer) team to meet the conditions of a valuable endowment, or they won’t be able to keep eating nine meals a day, and no wizard worth his pointy hat can tolerate that!
