what job did cosmo kramer have?

Kramer also drove a horse carriage in "The Rye" and he was an actor in "The Stand In" Mickey got him the job on a soap opera. Kramer also worked for free in Brandt/Leland because he used their bathroom in "The Bizarro Jerry."

It was H&H bagel and he left because they went on strike, he said they picketed for a while but nobody would let them use the bathroom so it put a crimp in their solidarity, lol. Seinfeld is best sitcom ever.

Besides that, he created the coffee table book that some people wanted to turn into a movie abd they paid him a lot which in the show he says " let's just say I won't have to worry about working for a while, a long while."

Heh, but don't forget, he had Kramerica Industries to tide him over while he was on strike. ;)

lol Kramer was hilarious in Seinfeld. H&H Bagels was great. He also tried to invent the cologne from the beach. Didn't someone else beat him to it? He opened up the Alex Theater. Tried to get into the trench coat business with Jerry's dad. Then he retired randomly when he really never worked at all.

He worked (very poorly) in a donut shop. He was on strike for several years, but has been fired!

he was a inventor. he invented how to waste time in a pleasant mode and with no money
