Intro. Swap Sans has managed to get his hands on a magnifying glass and wants to show it off to the other sanses! (Fell, Classic/UT sans and Swapfell) They all decide to see what is on their papyrus's minds while theyre completely oblivious to the situation and all starts off well with swaps papyrus (US papyrus) thinking about cigarettes, fellswaps papyrus (FS papyrus) thinking of a bunch of math and science equations, fells papyrus (UF) thinking about spiderman rubbing his hands on his body (iykyk) until they get to UT/classic papyrus.... they see something thats makes all of them extremely flustered as it involves some thoughts about classic sans, but what were those thoughts to make everyone blush so much? You can choose to have them read your mind too if you like but remember it shows everything thats on your mind

Mind Reading Magnifying Glass!
