I'll soon start my next #DnD campaign, and I've decided to start with a classic - the PCs all meet in a tavern. Now, the PCs intended to meet in a tavern and have plans to go elsewhere (the city of Ptolus, if it matters), but I want to start the campaign to start in a lively manner.

Which means populating the tavern with all sorts of weirdos for some good role-playing opportunities. Any suggestions?
