Eddie Valiant: Roger? He chickened out on me back at the studio.
Jessica Rabbit: No, he didn't. I hit him on the head with a frying pan and stuffed him in the trunk. So he wouldn't get hurt.
Eddie Valiant: Makes perfect sense.
Bob is about to do something that Charlie considers stupid attempting a Heroic Sacrifice, becoming The Bait, or otherwise putting himself in danger. Charlie could try to reason with Bob and persuade him not to go, but he takes a much faster and more direct option.
He punches Bob in the jaw. (The gut and/or solar plexus are also popular areas.)
Nine times out of ten, this will put Bob out like a light, but even when it doesn't it still subdues him long enough for Charlie to take his place or forcibly remove him from danger. Bob may be cursing and raging (or even attempting to return the punch), but Charlie will brush him off and insist that he only did what he had to do.
A subtrope of Cruel to Be Kind, since this sort of treatment hurts, even if it saves Bob from worse. Since one hero attacking another looks really bad out of context, this is a common source of Superdickery.
See Kind Restraints for a softer version of this. Compare Percussive Shutdown when this tactic is used against an object rather than a character. Can result in Percussive Therapy if the recipient of the hit has been a source of frustration for the person doing the hitting. A common reason for this is that the character punching you out is More Expendable Than You. Compare Get a Hold of Yourself, Man!, Dope Slap and Don't Say Such Stupid Things.

- Natsu inverts this on Erza, knocking her out with a punch to the stomach in order to fight Jellal for her.
- Yu-Gi-Oh! has the first duel between The Pharaoh and Dark Bakura. Dark Bakura has just set Man-Eater Bug in defense mode (read, anything that attacks it sets off its ability, which kills any monster on the field, and it's set to go off next turn anyway). Tristan attempts to attack it and take the ability to save his friends. This earns him a sword hilt to the stomach, courtesy of Flame Swordsman!Joey, who proceeds to do it himself.

It fails because Hyoga (with a gaping hole in his chest) and Seiya show up just in time.
- In Sengoku Basara at one point Masamune gets injured during the fight with Nobunaga. He faints while riding away on his horse (don't ask) and his faithful retainer, Kojuro, gets him to safety.

He insists on rescuing his men despite his weakened state, while Kojuro attempts to stop him. The two battle a bit, then Kojuro takes advantage of Masamune's still sensitive wound and knocks his lord out with a blade hilt to the head. One of the men who had managed to escape the kidnapping (and whom delivered the news) yells at Kojuro, asking him why he did that. Kojuro doesn't respond, but it's clear by the look in his eyes that his actions were done out of a deep love and sense of duty towards Masamune. Kojuro then borrows Masamune's swords, promising to rescue the kidnapped men himself.

Skurge knocks Thor out and tells Balder, "You and Thor have a drink when you are next in Asgard and laugh Skurge's last laugh together. I will hold the bridge." Skurge then holds the bridge with two M-16s, going down in an absolutely classic Dying Moment of Awesome. Or, to quote the closing narrative;
They sing no songs in Hel, nor do they celebrate heroes. For silent is that dismal realm and cheerless.But the story of the Gjallerbru and the lone god who defended it is whispered across the Nine Worlds. And when a new arrival asks about the one to whom even Hela bows her head, the answer is always the same.He stood alone at Gjallerbru. And that answer is enough.

- They Live has a scene similar to this, in which two barely acquainted people proceed to beat the crap out of each other for a full five minutes over one getting the other to put on a pair of sunglasses that let the wearer detect all the hidden brainwashing messages in popular media.

- In The Dark Knight, Bruce Wayne is having a party in Harvey Dent's honour, and The Joker shows up at the penthouse looking for Dent. Bruce sneaks up behind Dent, puts a sleeper hold on him til he passes out, then locks him in a closet.

Thus, Alexander survives where Richard died.

- Buffy the Vampire Slayer: Buffy applies some to her watcher, Giles, on more than one occasion.
- The original was in "Prophecy Girl", wherein after Buffy has her 10-Minute Retirement over her prophesied death and the associated She's Back moment, Giles tells her he is going to face the Master in her stead, and "there's nothing you can say that can change my mind." Buffy replies that she knows, and then roundhouse punches him. Thud.

He thinks that as an older and more senior officer, it's him who should deal with Simpson, not Hornblower who is just a boy in his eyes. Simpson is wounded, Clayton is gutshot, living just long enough for Hornblower to come round, reach the shore and listen to his Last Words.

- Danny Phantom: Happens in "Reign Storm" when (in no particular order) Maddie, Jazz, Mr. Foley, Mrs. Manson, the mayor, civilians, and the police push each other to the ground fighting over who will fight Pariah Dark and possibly die in the Ecto Battlesuit. We even get this little gem:
Danny: I thought I was going to have to blast everybody with a ghost ray, but this is much more efficient.
- In She-Ra and the Princesses of Power, Entrapta's attempt to warn Hordak about his activation of the portal that would destroy reality is prevented when Catra's overgrowing obsession to defeat Adora forces her to knock her out with a paralyzer.
- In the first episode of the X-Men cartoon, Cyclops orders a retreat, but Wolverine refuses to abandon Beast and Morph. Because going back would be suicide, Rogue uses her power on him, knocking him out; they carry him out as they retreat.
