The answer that will get me in the least trouble: my wife.
But choosing one person to be stranded with is hard. You need a person who compliments your own skill sets to allow for greater chances of survival and rescue. Your choice should be someone who is physically fit and reasonably intelligent in a variety of subjects. Or you could just choose someone who would make your final days as pleasant as possible, making the sex with until neither of you have the energy or will to go again.
I can tell you, however, one person I would NOT want to be stranded on a desert island with: Roy Hinkley. You may not recognize that name, but you’d know him if I called him by his more common moniker, The Professor. Yes, that Professor. The man who could make a radio from coconuts but couldn’t fix a hole in a boat. I mean, one thing the island had an abundance of was trees, you’d think he’d at least make a raft or a canoe or something. Given the amount of time they were on the island, he could have made a yacht!
Of course, I can’t bag on the Prof too much. Who’d really want to leave an island that counted Ginger Grant and Mary Ann Summers among its inhabitants? I certainly hope he was tapping that. Both of that. I know I would. In fact, I’d probably engineer a few “accidents” to eliminate my competition in that department to improve my odds. Yeah…
Crap. The wife is going to read this and I’m going to be in trouble. So, uh.. my wife. If I was stranded on a desert island, the one person I would bring with me would be my wife.
