- Becker: The title character thought he had a Christmas miracle when the package he meant to deliver ended up being delivered, despite him being stuck in traffic and dealing with a hitchhiker. Turns out the package was Becker's gift; the hitchhiker stole it. The package had already been delivered by Becker's secretary. However, Becker is actually happy about all of this, because he "always thought Christmas sucks," and can now prove it. After walking out, a diner patron delivers the line "You had to tell him."
- In the Buffy the Vampire Slayer episode "Spiral", Dawn says "At least things can't get any crazier. Right?" followed immediately by an arrow puncturing the wall of the mobile home they're riding in, the beginning of a siege.. Buffy replies, "You realize this is your fault, right?"
- A similar event occurred in Season 2's episode "School Hard"
Xander: As long as nothing really bad happens between now and then, you'll be fine.
Buffy: Are you crazy? What did you say that for? Now something bad is gonna happen!

Willow: Not until some dummy says, "as long as nothing bad happens."
Buffy: It's the ultimate jinx!
Willow: What were you thinking? Or were you even thinking at all?
- Being a Genre Savvy show with many references to pop-culture, this inevitably turns up on Chuck. Many times, Sarah or another character will make a comment on how a situation can't get any worse, only for Chuck or Morgan to call them out on it.
Sarah: So there's a stolen Intersect out there somewhere.
Casey: Guess we're not retired after all.
Sarah: Well, it doesn't change the plan. It just means we have one last mission.
Casey: My God, Walker.
Chuck: Things never turn out well when you say "one last mission!"
Sarah: Is this because of some stupid movie?
Chuck & Morgan: YES.
Casey: You never say "one last mission."

Carter: You had to say it.
- Get Smart series uses this as Running Gag, every time main character gets into trouble.

- LOST: In "This Place Is Death," the left-behinders need to get to the Orchid to stop flashing through time. Upon arriving at the station, Juliet remarks, "Thank God! What are the odds that we would end up in the same time as this thing?" They immediately flash to a much earlier time. Sawyer replies, "You just had to say something!"
A variation occurs an episode or two later, when our heroes are paddling in a canoe while being pursued by people shooting at them. The situation looks grim, but then the sky starts to flash. Sawyer turns to the sky and shouts "Thank you God!", only to find that they've flashed in the middle of a tropical storm, still in their canoe. Cue Sawyer shouting at God "I TAKE THAT BACK!"
- This happens on Misfits whenever the group are trying to convince themselves that things are under control, then Simon instils paranoia in them all by detailing the worst case scenario with gloomy relish:

Nathan: Now WHY would you say something like that?!

Blake: Aw, you had to say it, didn't ya?
(Blake points to another part of the beach where Kelzaks are shuffling by)
(Kira is picking all of the green MnM's out of a jar per her new boss's orders)
Kira: This job couldn't get any worse.
Kira: Now, why did I have to say that?
- Then we have the team-up between Ninja Storm and Dino Thunder ("Thunder Storm", from the second half): Hunter, Blake, and Cam are forced to go spelunking in the Abyss of Evil to reclaim their morphers before they join the fight against Lothor and Mesogog. They find one easily:
Cam: The Samurai Amulet!
Hunter: I can't believe there's no one guarding it.
Blake: You had to say it, right?
(Hunter shrugs regretfully)
Tyzonn: That was exhausting.
Rose: Let's get moving before someone else comes looking for these relics.
(Will detects someone coming with his super senses)
Will: (coldly) Had to say somethin', didn't you?
- It also does this in "Once A Ranger Part II", when Red Ranger Mack is searching for a MacGuffin in a forest:

Mack: (wincing) Next time, Mack, just keep your mouth shut.

- Inverted in this hilarious gem from "Enemies"
Jacob: We're not gonna make it!
[they make it]
Jack: Excuse me. I distinctly remember someone saying "We're not gonna make it!" I think we made it.
Jacob: I'm sorry, I overreacted. At the time, it looked very much like we weren't going to make it.
Jack: Yes, well, next time maybe you'll just wait and see.
Jacob: And blow the last chance I might ever have to be right?
Sam: Welcome to my life.

- In Season 5, Steve and Pete have this when the only way to neutralize an artifact is for a nerdy guy to win a fight against a knight, with said knight being an apparition from the artifact.

(Enter apparition, a menacing knight with a helmet from which black fog is flowing out, and a skull-shaped mask hiding all of his face except for a pair of Glowing Eyes of Doom, red, no less.)
Pete: Eh, you had to ask.
