not technically a chromecast, but I do remember that one time where I accidently played an old video of mine (now lost media) where it was a fake broadcast of a SML "lost" episode or something (it was actually a YTP if i recall) airing on Nickelodeon via that link smart TV option on the YouTube iOS app, my dad was watching TV at the time this happened, I think it was in around 2017 (when I was about 10 years old)
I now hate SML. (but not for this reason)
