In "The King is Back," Arturo gets mistaken for Luciano Pavarotti. He isn't very amused.
Arturo: I am not Mr. Pavarotti! Mr. Pavarotti is an Italian! He speak-a like-a this! Do I speak-a like-a this?! No! Why?! BECAUSE I AM AN ENGLISHMAN, YOU BLISTERING IDIOT!!
In "The Dream Masters," Arturo repeatedly blames Rembrandt for what happens to Wade, thinking he had fallen asleep on the job. He is later informed that the Cryin' Man had been drugged into unconscious. Arturo tells Rembrandt this and apologizes. Naturally, Rembrandt takes the opportunity to drag it out to the point of frustration.
"DON'T PUSH YOUR LUCK, MR. BROWN!"
In "The Guardian," Arturo has a new zest for life and is willing to try anything. This culminates with him bungee-jumping off a bridge.
Arturo: Pull me up, Mr. Brown, and let me do it again!
Rembrandt: How do we get him up?
Wade: You don't know?
In "To Catch a Slider," the others discuss the possibility of robbing a jewelry store to get a jewel needed to power the malfunctioning timer. Rembrandt proves to be the Only Sane Man:
