Not quite a Seinfeld Reunion
So it isn't as good as a Seinfeld reunion but this is about as close as we are going to get...
Jerry Seinfeld is ordered to visit the CEO of Crackle Dick Corcoran (played by Kramer / Michael Richards) who believes the company is being held back by 'snap' and 'pop'.
Ultimately, the viral video ends with a 'to be continued'. It aims to promote a new show 'Comedians In Cars Getting Coffee' and it's affiliation with Crackle.
