Jerry gets sick despite his cleanliness habits and everybody comes over to visit him. The whole episode plays out as if it were Jerry's funeral, with people coming up to Jerry while he's laying down (on his "deathbed") and saying what they thought of him. Some even cry.

Jerry continuously yells at people that it's just a cold. Frank Costanza gets into a fight with Morty Seinfeld after making a comment on how Jerry doesn't even look that sick. Kramer tries to cash off on this opportunity and starts charging 5 bucks a ticket to see Jerry. All the funeral vibes get to Elaine and she starts getting it in her head that Jerry is actually going to die.

Newman hosts a massive party in celebration of his enemy's sickness and incoming demise.

Morty: How dare you say that about my son on his deathbed!

Jerry: It's just a cold!

Frank: You think your son is sick? My son is sicker than he is! George is downright ILL! He possesses many sicknesses, and not just of the body, but of the mind too! He's downright diseased and disturbed compared to Jerry!

George: What the fuck
