NORTH CENTER — If you were looking for a reason to stay in your pajamas all day, here's one: free beer.

In honor of the upcoming release of its barrel-aged Imperial Pajamas stout, Begyle Brewing is hosting a contest with a six-month membership in its Community Supported Brewery program as the prize.

Here's how to enter: Stop into the brewery, 1800 W. Cuyler Ave., dressed in flannel pajamas, by Nov. 18.

Multiple entries are acceptable, limit one per day; must be age 21 or older.

"Does a more delicious or lazy contest even exist?" the brewers posted in the contest's rules.

Participants will also receive 20 percent off their tab at Begyle upon entering the contest.

One caveat: a simple flannel shirt doesn't count. Entrants must wear a full-on set of flannel pajamas (mismatched top and bottom will do).

The winner will be announced Nov. 18 at the Imperial Pajamas release party.
