The Adventure Zone TVtropes page has some weird aversion to Taako and Lup’s last name. I’ve edited it to say “Taako Taaco” and “Lup Taaco” three times now, the last two times I even gave sources, and they keep changing it back within a day. This time I even cited that the wikia and wikipedia pages list his name as such.
Their reasoning is that “it was said as a joke”, but so was Merle’s middle name?? Like, they said “Merle Hitower Highchurch” exactly once, but that’s definitely canon.
