Years ago, I pitched a comic strip idea where a man and a dog lived in an apartment, but the character’s typical roles were reversed. The dog went to work every day and was the breadwinner, while his owner stayed home and caused trouble.
In the end, no one (including me) thought it was ready for the big time, but to this day I still like the basic concept.
Every so often, I revisit those characters in a cartoon like this one. It’s like seeing old friends again.
