Some more things I've heard:
Master Gracey has a special narration whenever Chuck is in the stretching room. After getting his ghosty @ss kicked for calling Chuck a "foolish mortal," he now says "Welcome, foolish mortals...and Chuck Norris."
The last time Chuck rode through the attic, he screamed back at those guys who pop out from behind the graves. They haven't been heard from since.
When Chuck rides the Jungle Cruise, the skipper doesnt say a word. This is because of the unfortunate incident involving the young man who wouldn't "shut up with all those corny-@ss jokes," whose four prosthetic limbs are working out pretty well.
After demanding "extra thunder," Chuck now has his own special circuit at Big Thunder Mountain Railroad, which actually crashes through the mountain. Chuck gives it a 3 on thrills, but says it's an improvement.
