Quote from Tim in The Longest Day
Jill: But there is a chance, a very slight chance that it could be malignant. She said that it's usually very treatable. It also could be something they call hypothyroidism. Tim: Hypo what? Jill: It's an underactive thyroid. It just means he'd have to take a pill every day for the rest of his life, but other than that, he'd be totally normal. Tim: Ahem, boy... So it's either a lump or hypothymaster? Jill: Hypothyroidism.
