Upon entering his house, Mr. Linux is carrying what appears to be rolled-up carpet.
When Linux falls asleep, his hat is on backwards. When he wakes up and finds the doll, his hats is on forwards. When he runs out of the bedroom, it is backwards again.
After entering the Doom House, Reginald P. Linux takes off his sunglasses a total of three times without ever putting them back on.
The scene in which Mr. Linux confronts his tormentor shifts from Mr. Linux's bedroom to his living room between shots.
Linux isn't wearing his sunglasses when the cop comes to the door. When the cop tells Linux that he's living in a doom house, Linux is wearing his sunglasses. In the next shot with Linux, his sunglasses are off again.
Linux claps his hands together after throwing the doll out the back door. The clapping sound is still heard after he puts his hands down.
