You Just Had to Say It

"Harold: "I guess you're right. But at least things can't get any worse." George: "Aaaaugh! You did it again! Now when you turn the page, something even worse is going to happen! You've gotta learn to keep your mouth shut at the end of these books!""

- Captain Underpants

Stock response to many an egregious Stock Phrase, especially What Could Possibly Go Wrong?. Essentially Lampshade Hanging by the Genre Savvy of Tempting Fate. Simply put: One should never say that it can't get any worse, because sooner or later, it will. Usually preceded by frantic, ignored pleas of, "Don't say it, don't say it, don't say it... You Just Had to Say It, didn't you?!"

Occasionally said by the speaker to themselves, after the fact.

Common variants include:
 * I/You had to ask!
 * I/You had to open my/your big mouth!
 * Sorry I asked. (original speaker only)

 * From the Ed, Edd 'n' Eddy episode "Sir Ed-A-Lot"
