I think I'm gonna reread the whole 'everyday' arc again. That's like 9 volumes or so. I read a fanfic today where Goku was pulling out charts and stuff (like you do) and a bunch of people were going 'LIKE WHEN THEY TEACH TSUNA TO SWIM!' a chapter I totally didn't remember. So I looked it up el quiko via wiki and then hopped over to onemanga.com and read it. Oh Gokudera. I heart you so bad.
The entire chapter sums up the campiness that was Reborn (why'd you get so serious on me?) pretty well. You can read it here. Seriously, I was rolling around in my bed having a giggle fit. I think I might yoink that panel of Goku with the chalk board and use it for my next intro. But then I'd have to clean it up, and god knows photoshop hates me... We'll have to see.
Oh Reborn, I love you.
