Comedian Mike Birbiglia, author of the best-selling book Sleepwalk with Me, is spending a week in a window display at the Herald Square Macy’s in New York City. The stunt is part of an effort by Downy Fabric Softener to promote “Clean Sheet Week.” The idea for Clean Sheet Week came from a National Sleep Foundation Bedroom Poll conducted last year. The poll found that seven out of ten people claim to get a more comfortable night’s rest on sheets with a fresh scent.

Birbiglia’s stay in the display window started on Wednesday. He’s going to sleep in Downy sheets till February 1st. Here are some highlights from his press conference yesterday:

You can hit up Birbiglia on Twitter (@BirBigs) or visit the Downy or Macy’s Facebook pages to interact with Birbiglia while he’s on display.
