I think ehh, kinda think that this is medially canon. I'll give you an example.
"I'm off duty for the duel, sweetie, but hey, if you can take me, I might look into your case, you in?" - Sheriff Sandy, Cosmic Shake. AHEM? I mean, she says it sternly good. But (BE HONEST WITH ME HERE PEOPLES) but is she trying to, case in point, "Flirt" with Spongebob? IS THIS CANON-Just joking, but is she flirting with him?
