you could
buy 4 4 fingered kit kats at the start of a week, have 3 fingers of the first kitkat on monday, the remainnig finger of the first kitkat plus two fingers of the second kitkat on tuesday, two fingers from the second kitkat on wednesday with a single finger from the third kit kat, the remaining 3 fingers of the third kitkat on thursday and then round the week off with 3 fingers of the fourth kitkat on Friday. Obviously great care would be required to ensure that any partially eaten kitkats are placed in an airtight container to ensure that they do not deteriorate overnight prior to the rest of the aforementioned kitkats consumption. The remaining finger could be utilised any time during the week as an emergency finger. Say for instance the secretary was feeling a little blue you could rush to her aid and offer her an emergency finger to put a smile on her face, or perhaps if your blood sugar level were to drop dramatically at any time of the week you could give yourself an emergency finger to put a smile back on your face. If you find that there has been no occasion during the week to utilise the emergency finger you could bring it home with you for consumption over the weekend or shove it up yer bum and tickle your prostate with the wafery goodness?

you see
this was viable back in the days when kitkats were wrapped in proper foil that you could then iron with your finger on your desk after consumption. Now they're in plastic, you need a third party storage solution.
