Season 6, Episode 17: "The Kiss Hello"

Yeah. All right. I gotta go.

-Hi, Jerry. -Hi, Mary.

Listen, I've decided I can't kiss hello anymore.

I'm sorry. It's nothing personal. It makes me uncomfortable. I'm sorry.

-Hi, Jerry. -Hi, Louise. I was just telling Mary...

...how I'm not gonna do the kiss-hello thing anymore. I'm sorry.

I just can't do it. It's nothing personal.

It's just that I'm not really able to do it. Thank you for your cooperation.
