A Room of One's Own is an episode of the ALVINNN!!! and The Chipmunks series.
After squabbling with his brothers, Alvin convinces Dave to give him his own room, but soon realizes living alone isn't what it's cracked up to be.
After Alvin and Simon are involved in an argument over stinky laundry, Dave breaks it up. While Dave is reminding Alvin of previous arguments, Alvin's dirty clothes interrupt his train of thought so he takes them to the basement where Alvin convinces Dave to give him a chance to prove he's mature enough have his own room. Simon corrects Alvin on mature actions and Alvin does the dishes, vacuums, dusts, and reads an encyclopedia to give the illusion that he's mature. Dave responds by giving him the only available room in the house: the basement. He moves in initially very excited to have a "wolf pad," but finds that the room is very quiet and lonely. The next day, Brittany and Jeanette catch Alvin impersonating his brothers as plushes. He plays with himself, while his brothers are also lonely, but Simon isn't willing to forgive Alvin. The Chipettes learn without a doubt that the boys miss each other and are too prideful to admit it so Brittany comes up with a plan to trick Alvin into reverting to his old behavior. Once he starts misbehaving again, Dave forces Alvin to move back in with his brothers. They are happy he's back only to be involved in another brotherly argument.
