So, I was just watching Homer's Triple Bypass for about the 50th time and I noticed an error in the final scene. After the operation, Homer's heart is beating away strongly, and we get a nice internal view of it. Except, the vena cava are red in colour while the aorta is blue, suggesting that Homer's heart is pumping in the opposite direction! That's what you get with Dr. Nick, I suppose.
Anyway, I'm less than two months into this and I'm already finding the more questionable things on "serious" dramas like House intolerable. It's most distressing. :\
