1)to spend time with beautiful women coming on to you with no possible consequences (it was the sixties), and yet avoid getting laid for seven years. I mean, WTF?
I'm pretty sure Herman Munster or Eddie Haskell wouldn't have pulled a Gilligan if they had their druthers.

A person that is part of the television show, "Gilligan's Island". The whole story line has to do with them going on a trip on a boat, and then a storm come and they get casted away, and they land on a desserted island that isnt on any map. They had like 100 chances to get out of the island but one person always messes the plan up, guess who? Gilligan. I don't get why they dont just kill him he's the one that gets them stuck on the island and messes up their plan to get off it.
