Continuity mistake: When the man from the hand modeling agency is talking to George about Ray, he lifts up his right arm to make a claw with his hand, and as he does so he has his left arm holding up his right. After a cut, the man's left arm is suddenly hanging down, no longer supporting the other arm. (00:16:05)
Chosen answer: George does mention his brother in the episode "The Parking Space". They actually really never mention anything that contradicts the fact he had a brother though, it just isn't mentioned.
