Dennis the Menace tries to be relevant, fails

First of all, I've been paying my bills online for about 20 years, so it's more alarming than funny the artist/writer just found out paying bills online is a thing; secondly, in which universe  does Dennis the Menace live in which postal carriers wear jackets with lapels and neckties?

 

Dennis the Menace works blue

Probably more about the Mitchells' sex life than we'd like to know, but I like when old comics try something new.
