When the Tourist Twoflower first came to Ankh-Morpork, he came to the Broken Drum, where he met the wizzard Rincewind. He sold Broadman an Inn-sewer-ants-polly-sea, explaining it as a bet on the building staying upright. Broadman decided to burn down the pub and collect the inn-sewer-ants money, but unfortunately died in the fire. The fire spread, burning down half the city. It was later known as the Great Fire of Ankh-Morpork.
