Dr. Bon's notes on the uninspired couch potato character roles:
Oh, this one is easy. There's a selection of yoga-joke Namastay on the Couch t-shirts and hoodies, which is a funny and easy costume for any unemployed, moocher, couch potato character. Also, you can wear The Dude costumes, cat lady costumes, or just get a bathrobe and mess up your hair!
