Dr. Legshooter, PHD

So I'm riding the bus and I see three old timers talking about old times. I'm not really trying to eavesdrop but they are talking loudly (I only assume it's because they can't hear very well) and I can't help but overhear the conversation (it's more like a dissertation because the other two are not saying much). So this guy is going on and on about how shooting someone in the leg used to be a minor crime compared to today because you get much more time in jail in comparison. Wait. What? How would he know this? Has there been a Harvard study on this? Has he been conducting this study and who has he been shooting to get this data? Did he take up Shooting People in the Leg as a trade from Washburn Trade School when he was young and now he is doing his research for his doctorate in leg shooting? Before I could ponder the implications of his findings I notice he is getting off the train at the 63rd St. stop. (Pause) I was going to go to the shop today but looking at my legs I decide to go home instead.
