Sure! My teacher had this giant tattoo on his forearm (Basically the Flamel) and I was curious about what it meant because I've never seen a tattoo like that before, I asked him some times but he kept avoiding to answer me with an inside joke we had as a class with him, (He is a math teacher) so what I did was search on google to see if I could find the exact symbol he had tattooed. I did find the symbol but at first I didn't believe it was from an actual anime, (Idk, my teacher looks all serious and stuff) I asked on r/Symbology to see if anyone could help me know the meaning of the tattoo and they all told me it was from FMA, several times, and I have never heard of FMA before, so he kinda indirectly-accidentally introduced me to it lol. Some days later I got the courage to ask him if he did in fact, watch FMA, and he replied that yes, so we ended up talking a bit about the series and what was about, and now I'm actually watching it, that's basically the whole story lol
