In the small room after Woten's office (where you find the Aesir building plans), there is a small picture that you can shoot off the wall, revealing a button. Pressing it will raise the couch on the other side of the room, revealing a staircase down to a "private area". In it there is a big screen TV you can use to play a 3DRealms-themed parody of Star Trek. In the adjoining room there is a bed with chains next to a closet full of bondage gear.
