Really, what is Arnolds last name?
You are not alone in asking this; it’s probably the most-asked question Nickelodeon gets (especially now that the other “really asked question”, “What happened to Chuckie’s first mom on Rugrats?”, has been answered). Arnold doesn’t have a last name yet (despite what he said on one of the “Cafeteria Confessions” – it’s like when they’re about to tell you exactly where “Springfield” is on The Simpsons, only for something to happen and you don’t find out). Craig Bartlett said that he might give him a last name, but it’s not definite. (Note that Rocko on Rocko’s Modern Life never had his last name revealed either (although according to Joe Murray’s original design of the character, his name is “Rocko Rama”), even though just about every other character’s last name was mentioned.)

At the time, 4040 Vineland was the Sunset Arms
