Aside from opening the bottom slot, Dean wouldn’t need to do much with all those Sams. They are a collective genius when it comes to climbing, and they’ll be bouncing around the inside of the machine in no time, knocking down the M&Ms first, then calling out for orders from their taller counterparts. Since they’re already there, might as well.

Dean would have to stay sitting there, fetching the food as Sam knocks it out of the rack, cackling all the way at the free food. 

(Not that the lounge doesn’t already have free food, but it’s the principal!)
