I know that. You did it first. Huh I just thought of something. You know how Poison Joke makes Pony Rockette look like an Alicorn without the powers, what if it caused EG Rockette to look pregnant without being pregnant?
She didn't use poison joke for that, she used tacos. Lots and lots of tacos. Half of which ended up in her booty.
F*ckin' fresh bread, brisket, homemade burger sauce (mix of ketchup and mustard along with a few spices), Pickles, and a slice of good ol' American cheese. Best food I've ever had.
Realistically. If things were in such a way where poison joke and the magical properties of Androgyne Oil were existent, I really wouldn't want to see those things mixed. Generally speaking, Poison Joke is a spiteful plant that makes ponies suffer for x period of time with odd effects. Using that in any capacity, without possibly purifying it first, could lead to nightmares like this. Granted there is a method for purifying Poison Joke, which is something I wouldn't know.
Yes and just the once, as far as I recall. They do worry about it in later episodes, but it always ends up being something else.
