Einstein, the Curb Your Enthusiasm star who died Wednesday at age 76, was the first guest on Seinfeld's Comedians in Cars Getting Coffee to make a second appearance. He also achieved something special when he got Seinfeld to laugh on the set of Curb. Seinfeld's video features a montage of Einstein's appearances of Comedians in Cars in Seasons 1 and 9. "We made this little tribute to one of our favorite people ever in the world of comedy, the one and only Bob Einstein," Seinfeld tweeted.
