Nick the Banana. Thread the needle with the fishing line. take the Needle, and, at each "seam" in the peel stick the needle through and out the next seam. Loop back into the second hole and out of the next seam. continue until you've come back out of the original hole. You've now a loop of fishing line around the actual 'nana. Pull both ends of the loop and it closes and slices the 'nana inside the peel. Repeat half a dozen times, then return the 'nana to his packed lunch. Then Wait. Eventually victim peels the banana, and lo-and-behold, the 'nana falls apart in neat chunks... Cue complete disbelief from the workmate and much hilarity on my part.
