I've written a strongly worded email to Bungie complaining about your constant and inappropriate reference of Joey and Billy as little. The size of their penis should have no bearing on how the RNG system works in Destiny and your own example is flawed as you state that Little Joey gets an exotic from a strike. If penis length were a determining factor of the likelihood of exotic item drops let me assure you I would most likely have all of them including ones yet to be released in the DLC. Seeing as this isn't the case I can only conclude your ill judged theory is hogs wallop.
