Just for laughs here, but in the late 2000s there was a Canadian homebrewer guy who had a youtube channel where he had an extremely know-it-all, condescending attitude and was obsessed with detailing the minutiae of homebrewing and particularly sanitation. he would wear a hairnet or plastic on his clothes because he would talk about tiny particles of dust entering the carboy and ruining your beer when you opened it.
he was a large, semi-muscular guy in his late 30s with a loud voice and played "audience cheering" SFX during his talks. maybe it was a character he was playing up but he was very amusing to watch.
anyone remember his username or anything? i want to see if those vids are still up.
