My most embarassing moment happened just recently, I think. In my thread "Saruman's ending (PJ's way)." We were talking about how Legolas supposedly shoots Grima from off the top of Orthanc and kills him. In my moment of brainfarts I said, "anyway wouldn't Saruman pull a Gandalf and deflect Legolas' arrow." Luckily,
SpM, caught this mistake, and said "Wasn't Saruman already dead, before Legolas shot the arrow?" I think I'll just edit that post, and say, Grima will catch the Arrow before it reaches him
