I just noticed a few times where Gilligan says things in a really camp way, whether unintentionally or not.
In Slave Girl where he's in the hut with the Professor and he says "Do you have any other ideas?"
In It's A Bird, It's A Plane where he says "Buy insurance?"
and in Goodnight Sweet Skipper, "Harris is the one with the radio manual. If anything happens to him, somebody grab the book!"

It's way too cute the way he says these things. :D

When he says to Mrs. Howell, "Why don't you wear your blue dress?"
