http://donjon.bin.sh/5e/ is a great resource for randomly generating encounters, locations, or NPCs on the fly. Dont like what it gives you, just hit refresh until something catches your interest. It's nice to have a website for that type of stuff these days. I remember using a book called The Toolbox and rolling a d20 or percent dice to generate tavern names on the fly from a table.

And here's your spell to get schwifty . A buddy of mine has used that a few times in our current campaign to good, comedic effect.
