Its doubtful that there are two character that would get along better than Jughead Jones and Dagwood Bumstead. Okay, aside from Dagwood's love for his wife Blondie, which Juggie just wouldn't get at this point in his character development (if ever), the two share a much deeper love.
Imagine, if you will, Mr. Bumstead making one his legendary Dagwood Sandwiches for the lad. This would be an experience that would exceed any other in Jones' life! And they both get plenty annoyed with nosey busybodies like Veronica Lodge and door-to-door salesmen.
And yes, before you ask why Dagwood... he appeared in 46 issues of Blondie published by Charlton Comics from 1973 to 1976.
