Imagine you're at the mall, and a genie pops out of nowhere, and asks "Hey, you can have one wish. If it's too big a wish though, I'll dump sandy mayonnaise on you instead."
After the shock of seeing his sandy mayonnaise jar collection, what's your wish?
Remember, it can't be too big, or ELSE. Try to come up with it in less than ten seconds.
Mine: "I wish for a yellow helium balloon that lasts forever." (came up with it on a whim, after typing up the instructions above.)
