Unseen academicals

Unseen academicals. Football has come to the ancient city of Ankh-Morpork. Not the old-fashioned one, but the new, fast football with pointy hats for goalposts and balls that go gloing when you drop them. Now the wizards of Unseen University must win a football match without using magic, so they're in the mood for trying everything else. This is the 32nd Discworld novel.
