This is a parody of another short comic, I think it went by "American Mother, American Son" but I cannot find it currently. The kid complains in the first panel about "Hamburgers and hotdogs every day" and "having his ballistic missile salute" or something along those lines. I think the mom was in a cowboy hat.
I came here for the brain fucking and was sorely disappointed that it was just a little antennae tickling inside her nostrils, but the ending was refreshingly wholesome so I think I can forgive the tagging.
