being a Seinfeld addict (I watch it literally every day), I can answer a few of these:
the bottle scam: Kramer/Newman wanted to return bottles to Jersey to get more money for them
a old sewing machine got caught under the mail truck, causing it to burst into flame ("Oh the humanity!")
Jerry's vomit streak: something like, 14 years, 7 months, 32 days and some odd minutes.
So here's my questions:
-What was George's first job on the show?
-What were the very first and very last lines ever said on the show?
-What was the "new" response to sneezing Jerry came up with?
-What did Elaine say to the woman at that party who said "I've lost my fiancee, the poor baby!"
-what was "the contest" about?
-easy one: Who does Jerry have a fascination with?
next?
