The scene with Nami hitting Luffy and then Sanji was hilarious, and the Sanji lines about Nami's shirt were perfect.
Overall a pretty good episode, I never noticed how shady Conis started acting in this episode before. I also never noticed how early the shipwright stuff was brought up, I mean I knew it was mentioned in Skypiea but it never clicked that we won't actually find one for almost 2 years. (watching episodes week by week instead of in bulk via fansubs is really different, it really makes me want DBZ to be dropped so we can have 2 One Pieces a week)
So, despite IQ Test being in the title we have yet to hear it said by anyone. In the original episodes when did we first hear "ordeals" mentioned by a character? So far all we've heard is Final Judgement, judgement, and challenge in regards to what Luffy, Usopp, and Sanji have to go through.
