Ok, the hat was legitimate, but it was really talking to Namur that made Fionna feel that way and she knew it. Granted, Namur flaunted his knowledge but he still was nice about it. In a way, when she thought about it? It was like having a kinda posse around, even if he was a teacher!

"Aw man, for serious? And here I wanted something to drive him nuts."

Hint hint.
