Welcome to Straight Dope, newbie! They call it straight dope because as soon as you read a few postings, you will realize that the people who frequent this site have to be high on something!
There has not been much mention of the Professor. By the way, did he have a name?
Anyhow, the Professor was obviously very intelligent, and he or his descendants could probably have found a way to start a genetics lab that could correct any genetic defects in babies before they were born.
But then again, it is a bit troubling to note that the Professor’s intelligence and resourcefulness seemed unevenly distributed. For example, he could make an electric generator (remember Gilligan peddling that bike made of bamboo?) or even a radio out of a coconut, but for some reason he could not repair a hole in the side of a boat.
There is another problem with including the Professor in the breeding population. Sorry folks, but I am convinced he was gay. I mean, look at the guy. In his thirties, unmarried, perfectly coiffed, clean and stylish sportswear, gentle demeanour, and he never once leered at Mary Ann in those tight shorts. Now, gay people CAN reproduce and do frequently do so. But what if the Professor was invited by Ginger to “come up and see me some time” and replied “Sorry, but I planned to go antique hunting?”
Then again, maybe Mary Ann and Ginger were lesbians. After all they lived together. Or how about this? Maybe Ginger was a Drag Queen! I mean, look at those clothes and that wig and tell me she wasn’t!
I remember watching Gilligan’s Island as a teenager and thinking the Professor was the handsomest man on the Island. But then it occurred to me that when your competition is Gilligan, the Skipper and Thurston Howell, the title of “handsomest man” ain’t sayin’ much.
Finally, you might be interested to know that there really are people whose family name is “Gilligan”. I know a guy by that name who was in the Canadian Navy. Can you imagine what this poor guy went through whenever he had to take the wheel of the ship he was posted on? Do you have any idea how many jokes he heard about a “three-hour cruise?”
