I've always wondered why in the game Baldi says "Wow you exist" and now I have the answer when Baldi was a child he had this teacher who was basically high 24/7 (hence his name being Mr. High) and when the children got the questions right Mr. High would say "Wow you exist" cause he's so stoned that he doesn't even recognize the students so yeah this is why Baldi says Wow you exist.
