When Mako-chan and Motoki are walking by the river, did you know that Mako-chan's shirt has the word "[BLEEP]" in it? It's not ----[BLEEP], it's not a word that ends with "-[BLEEP]" but it's "[BLEEP]" alone. I found that weird.
I seriously didn't notice that until you said it in your post (and I watched it 3 times). :o It was funny, I wonder how that escaped me the first time?
The Ami transforming part was in the beginning during the potato scene, when Makoto chokes on some potatoes. It was not all that funny because it only lasted about 2 seconds.
I have a shirt with drawstrings on both shoulders. They serve no purpose and just meant for style. Yet people like to pull on them and it annoys me to no end. For some reason people always think the 2 ends are attached even when there is a huge neckline in between completed with a neck & head attached.
