Julius and Jasper
Remember these two men in several cartoons, Julius and Jasper?
One classic one that was very short but great has Jasper (the dumb one) standing with one leg in the air. Julius comes by and asks, "Why are you standing with one leg up in the air, Jasper?" Jasper says, "Because if I put two legs up, I'll fall down." He then demonstrates this and falls. Julius says, "Makes sense. Sure."
Another one has Jasper crying and Julius asks what's wrong. Jasper says he lost his elbow. Julius says, "Don't be silly Jasper, there's your elbow." As Julius walks away, Jasper is exuberant, "Oh hooray! For joy! Julius found my elbow!" But then he turns somber again and says, " Julius, come back. I've lost it again!" And he cries once more. {This brings to mind the hilarious time when Ernie frets to Bert, "I lost my air! Oh oh! I lost my air!"}
In a third one, Julius is holding an apple and asks, "What can you tell me about this apple, Jasper?" Jasper takes it and starts eating it and says, "Well, it's round and red." He takes more bites. "And juicy and sweet." More munching. "And gone". He gives the core to Julius. Julius frowns. {There's Jasper acting like Ernie again - he ate his food!}
I think there were more, but none come to mind right now. Seems like there were at least a couple with Julius alone. One was something like Julius comes to a hole in the ground and stops and says to the viewer, "I'll bet you thought I was going to walk right in that hole." Then he jumps over the hole -only to fall into another hole that was to the right of it. The other solo Julius one I'm thinking of is him walking into a wall (he may have been avoiding a hole in the ground again and as he walks around it is looking at the viewer instead of where he is going and then bam! Into a wall).
