If you haven't heard of The Santaland Diaries, you need to learn about it. Holy cow, it was fabulous!
Here's a little show description from Portland Center Stage...
"Based on the outlandish and true chronicles of David Sedaris’ experience as Crumpet the Elf in Macy’s Santaland display, this hilarious cult classic features comic encounters during the height of the holiday crunch."
Tickets are limited and some shows are sold out, but if you can find tickets, I highly recommend checking it out. Keep in mind that this show is for the adult crowd, so keep the littles at home.
