Quote from Jerry in The Face Painter
Jerry: Did you call Alec Berg and thank him for the hockey tickets? Jerry: No. Kramer: Oh, Jerry, what are you waiting for? Jerry: What do I gotta call him for? I thanked him five times when he gave them to me, how many time I gotta thank him? Kramer: Oh, no no no, you gotta call him the next day, it's common courtesy. Jerry: No, I don't believe in it. I'm taking a stand against all this over-thanking. Kramer: Jerry, good manners are the glue of society. Jerry: Hey, if I knew I had to give him eight million thank-yous, I wouldn't have taken the tickets in the first place.
