The flavor text for the card Fat Ass from the parody set Unhinged has the flavor text, "Our lawyers say no matter how funny it would be, we can't encourage players to eat the cards. Hear that? Whatever you do, don't eat the delicious cards."
In an official website article, the author makes a point about the nature of Magic's goblins by offering readers several large red buttons to push. Pushing them (sometimes after several pushes) causes the text and graphics to become scrambled. Except the last button. That one gives a censored preview card for the new expansion.
Whenever your opponent plays something you've never seen before, it's a normal reaction to grab the card for a second to look at it and figure out what it does...Unhinged made this instinctive act come back to bite the player with Vile Bile.
