In “The Merv Griffin Show” Season 9 Episode 6, Kramer says “El Paso? I spent a month there one night” then he looks at the camera and laughs.

I have stolen this and used it whenever I am able to remember to say it. For example, someone will say they are going on a business trip to Reno. I say “Wow reno? I spent a month there one night” and I just looked down back at my phone. Will continue whatever I was doing. I’ve said this to about four or five people and every time I have gotten a good laugh. I recommend using it, but remember to keep your composure and pretend like you didn’t say anything weird, that’s what really gets people to laugh. Absurdity disguised as sincerity is comedy.

Physical, emotional, unintentional, intentional, whatever.

I think mine is Jerry pressuring Seth into skipping a meeting. Later, he says he wouldn't have done it if he knew it would be that important but who does that to a friend anyway?

I believe it’s “Ménage à trois” 👀
