If I'm being completely honest, I'd take all of the characters from The Office. But there's only so much room on the plane, so I'll take what I can get.
1. Dwight Schrute.
I feel like this one is obvious. He's a survival expert, knows how to shout directions in case of a fire, and would most likely bring a lifetime supply of beets, so. (CPR on the other hand, may not be his strong suit.)
2. Phyllis Vance.
Phyllis could probably knit us clothes, pillows, etc. Enough to keep us all warm and cozy. She may also be motherly enough to keep us all company. (We're leaving Bob Vance, Vance Refrigeration, at home.)
3. Robert California.
Because he's some sort of weird super genius and I feel like he is necessary to island survival.
4. Pam Beesly.
Again, very motherly, but also quick and witty. She's clever and creative. She can even bring Cece and Philip. She also may be able to draw a picture in the sand to catch a helicopter's attention and save us.
5. Jim Halpert.
He'll keep things light and make constant jokes, not taking anything seriously. And if we get too bored, he can pull pranks on Dwight, so, it's a win win.
6. Creed Bratton.
Just because I feel like some of the weird, random, comments he make could be useful in some odd fashion.
7. Michael Scott.
Because he clearly did really well that one episode that Dwight left him out in the forest alone. If we ever got bored and wanted to do improv or listen to Michael Clump, he's our guy.
