Laundry Room of the Brothers Strong
From Homestar Runner Wiki
The laundry room is presumably where The Brothers Strong do their laundry. It has a washer and dryer and the No Loafing Sign in it. Strong Bad once locked The Cheat in the dryer, although he really meant to lock Strong Sad in. Strong Mad later confronted Strong Bad about keeping Bubs' Concession Stand here. In narrator, the laundry room served as the set for the preview of Strong Bad's movie "Things That Go Dump In The Night", in which an unsuspecting Strong Sad looks in the dryer and is hit by a dead goose. By this time, the laundry room had gained a washing machine. In lady fan, The Cheat once again appeared in the dryer.
In the email redesign, Strong Bad updates the decor of the laundry room by adding a decorative border along the upper wall, and hot-gluing seashells to the dryer knobs, all for under 50 bucks.
