While walking around I saw five SGT. Frog cosplayers. I had watched the show before, and started naming while talking to them. The characters Keroro, Giroro, Kululu, Tamama, but I had forgotten the last guy's name off the top of my head. So I said, "Now who was that last guy?"
Ironically enough, Dororo's character has a running gag where everyone forgets about him and his name. So I passed it off as a joke once I remembered but it was fun.
Another incident happened during day two, I was leaving the Dealer's hall. I overheard a mother telling her red badge child to drink water because it was so hot. I myself was wearing Ouka of the Divine Fist Cosplay, bikini, fur upper chest, forearms, and feet, with a fur scarf. I had made a comment, "Oh my go, I am melting" and stuck my head in front of one of those large fans in the parking garage.
The Mother responded, "See how much she is wearing, and how hot she is? Go drink some water."
