We just switched DD to pull ups and I guess DH did not read the diaper where it says "back" on the back so he put it on backwards. DD eventually figured it out and said "Daddy put my diaper on backwards! He is so silly!"
ETA - I just emailed DH telling him and this is what he wrote back "Hahaha, did I? I was confused which way it should go. I thought about it long and hard".
LOL.
