I remember that scene from "Quest for Camelot" where Sir Ruber fused his arm to Excalibur to become absolutelly powerful.
Well, he doesn't expected that the sword could change into... this!
Excalibur: YOU FOOL! Do you want to hear about my legend? Sir Ruber: What the...? Excalibur: What's you favourite number between 1 and 12? Sir Ruber: Where's the freakin' sword? Excalibur: I am the sword! My legend began in the 12th Century! Wanna hear it? Sir Ruber: Oh God, what I've done... Excalibur: FOOL!
