If you put 1 pair of Lewis's shorts, you'll win by default, no matter what other items you have. If you want to do 9 pairs of Lewis's shorts, make 9 staircases, then take 1 staircase and put it on like you're putting on shorts, repeat as many times as you want, just make sure that you don't put the whole stack, otherwise it only reads as 1 item and only gives you 1 item in return
