Ferguson must have been absolutely wild with jealousy. Positively fuming. Burning with white-hot envy. Melissa Joan Hart posted a choice #tbt featuring 94 percent of the teen-girl heavy hitters of the ‘90s. Between Hart, Tia and Tamera Mowry, Jenna von Oy, Jodie Sweetin, and Andrea Barber, it seems like a perfect time in the cultural zeitgeist to have all of their characters guest on Fuller House. What’s that you say? That wouldn’t necessarily make any sense, given the various show universes and character timelines involved? Need you be reminded that we create the rules? We are the gods of television, and if we want Six, Clarissa, and the recently reunited Landry-Campbell twins to roll up to San Fran for a, let’s say, amazing hat convention, then so it shall be.
