Vend at a show and you will meet tons of people like that, often they try to impress their friends with their knowledge and you can't help but laughing inside when you hear the conversation.
It's ok not to know something but in that case people should not act like they do and claim they are right.
Best I heard are about Pied
"It's half albino"
"It will grow into it's color"
"It's shedding"
