Ok, got lucky and MANswers re-ran the episode with the answer to this.
It's Maxi Mounds, a stripper in Memphis and hers are 61MMM. According to the show, the Guiness Book of World Records also shows her as having the largest breasts in the world.

Yes doctor, I am sick.
Sick of those who are spineless.
Sick of those who feel self-entitled.
Sick of those who are hypocrites.
Yes doctor, an army is forming.
Yes doctor, there will be a war.
Yes doctor, there will be blood.....
