Quote from Cliff in For Real Men Only
Woody: Say, did his bellybutton fall off yet? Frasier: Any day now. Norm: What, what do you mean? Frasier: Well, you see, when the umbilical cord is severed, the remaining umbilicus stays attached to the naval for several days, during which time it, uh, comes to resemble a sort of shriveled, week-old banana. Cliff: Hey, you know, it's very funny you use that analogy because the, uh, human umbilical cord if memory serves is 90% potassium. Frasier: Stay away from the baby, will you, Cliff?
