In the Seinfeld episode The Serenity Now Frank Costanza is advised to say 'serenity now' aloud every time his blood pressure is in danger of going up, but he yells it instead. Do you have high blood pressure? Then maybe this t-shirt will help!

Looking to retire and move down to Florida? Then maybe Del Boca Vista Phase II is something for you! Just ask Morty Seinfeld about it, he was the president of the tenant's board for many years, until Jerry bought him a Cadillac.

What do you call someone who doesn't like going to the dentist? I'd call them 'normal' but Kramer would call then antidentite, just like he accused Jerry.
