@strangefour @floatybirb @josh0 Yeah, and IIRC the association between #WrongFrogs and the second movie came about because after everybody watched (the correct) Frogs that week, a few of us decided on the fly (no pun intended!) to watch (the "wrong") Frog as a palate cleanser. We used #WrongFrogs as the hashtag to mark toots associated with the double feature as opposed to the main feature.
A few people have kept using #WrongFrogs consistently for toots associated with the double feature, but it's not nearly so common anymore. I crunched some numbers and found that in recent weeks, generally speaking, #MonsterdonDoubleFeature is the most common hashtag for double feature posts, followed by WrongX where X is something specific to that week's movie (which was actually X in one case), with #WrongFrogs and a smattering of other Wrong* hashtags trailing behind those.
