This is the randomest thing since the common comparison to sliced bread
With my luck, I would've been stuck with a popular girl or three who treat me like I don't exist. In reality though, I probably would want to have this kid in my science class who wears NASA shirts and reads "The Lies They Teach You in School." He seems smart in the exactly-like-Sam-from-the-Lorien-Legacies-books way, and he can draw. In my unlucky world, the items I'd have would end up being a spatula, a goose, and a chicken bone...but if I had a choice, obviously I'd bring a Costco-sized palette of nonperishable food, a TV (you know those oldish ones with the plug attached), and a bar of soap. No one ever said the island didn't have any outlets or running water.
Marooned
If I were ever to be stranded on an island I would most certainly have the following items:
1. My IPhone. Even without a signal my iPhone is still a torch, and a source of entertainment and inspiration that would at the very least get me through the grim times.
2. A Solar Power charger for the phone.
3. A box of flares. These would be used for attracting attention from any passing shipping as well as a source of ignition for fires.
And, of course, my closest friend who I love and trust completely. His sense of humour guarantees laughter even in the deepest of despair, and he is a professional chef.
3 Hour Tour
I would bring an oversized Lazy Boy recliner, a kegerator full of Hop Valley beer, and a Rob Allen speargun. I couldn't choose between my wife and kids, so I'd have to bring Wes Anderson or Tom Robbins or Louis de Bernieres--any one of them would do, really. I just need someone to narrate away my insanity.
