We Gotta Stop Meeting Like This

A Stock Phrase involving two recurring characters who meet at least twice in the same awkward, confrontational or dangerous manner.

Maybe Alice and Bob keep meeting by running into each other, or while fighting off hordes of strangely dressed ninjutsu practitioners. Or maybe Alice and Bob, while enemies, aren't afraid to chat cheerfully while trying to beat the living daylights out of each other. If Alice and Bob do this repeatedly and under the same circumstances, one of them is likely to eventually spout the Stock Phrase.

Jokes and Humour

 * A woman is having an affair with her dentist. The dentist tells her one day "We've got to stop meeting like this. You're almost out of teeth."
 * Worth noting where this joke came from: When two people are having an affair, one of them might say this to the other to try to put an end to it, usually unsuccessfully. The joke is putting the phrase in a situation where they're obviously not meeting on purpose.

"Methos: We've got to stop meeting like this, people will talk."

"Ms. Piggy: We have to stop meeting like this.

Video Games

 * In Red Dead Redemption,  says this word for word to John Marston at the end of his story arc.
 * In Max Payne, Mona Sax says this to the titular protagonist upon meeting by drawing guns on each other for the second time in the game.
 * In the Hitman series the recurring special agent 47 keeps having to rescue says this eventually. 47 notes that it's unlikely.
 * In Star Control 2, if you let the Dnyarri mind-control you, it will compel you to seek out an Ur-Quan ship to get yourself killed. The first time this happens, you can reason with the Ur-Quan and he will let you go in exchange for information. If this repeats though, your character can say this exact line (which won't make the Ur-Quan any less pissed at you.)
 * Also, if you keep running out of fuel in deep space, the friendly merchants who come to rescue you will eventually say this.
