Tobacco Use in Seinfeld

Kramer gets kicked out of Monk’s after he lights up a cigar and meets people smoking on the street, so he invites them up to his apartment to smoke.

“Well somebody had to. You know, just because a person’s a smoker, that doesn’t mean he’s not a human being…these people aren’t just going to let themselves be flicked into the ashbin of society.”

Kramer quickly realizes the harmful effects, and his face begins to look like an old catchers mitt when he experiences a lifetime of smoking in 72 hours.

After consulting with his lawyer Jackie Chiles, Kramer sues the tobacco company but ends up settling for a Marlboro Man billboard with his picture on it.

After hearing about all the fun playing with her toy collection George asks Jerry to invite him over for dinner so he can get some play-time too.

And what better meal to make Celia drowsy than a nice Turkey dinner and a box of wine? What is that stuff in turkey that makes you sleepy?

“Tryptophan.”

Later, the whole scheme is revealed when Kramer invites Jerry onto his talk show for a Scandals and Animals segment.

“If you think you can drug me and play with my toys, you got another thing coming, buddy!”

After a few shots, Kramer starts acting goofy

“Boy that Hennigan’s goes down smooth. And afterward you don’t even smell. That’s right folks. I just had three shots of Hennigans and I don’t smell. Imagine, you can walk around drunk all day. That’s Hennigans, the no-smell, no-tell scotch”
