Kramer accidentally discovers a new life saving drug when mixing shampoo and patents it. George's mother needs the drug, but Kramer's upped the price 3000%. Jerry becomes addicted to opiates after his doctor prescribes them for his back pain.

GEORGE: Kramer, please. I'm begging you!

KRAMER: Sorry, buddy. No can do. This is capitalism, baby!

ELAINE: $3000 dollars for 10 doses? How much does it even cost you to make this stuff?

KRAMER: One George Washington.

JERRY: Ah, so you're this big pharma I've been dealing with recently.
