So, I’ve stumbled across a ridiculous set of coincidences between Trey and the other famous Trey Parker.
South Park’s Trey Parker: Real name, Randolph Severn Parker III Born in 1969 Actor, Singer, Songwriter Involved in Broadway Had a band in the 90s and early 2000s
E.Y.C.'s Trey Parker: Real name, Donald McKay Parker III Born in 1972 Actor, Singer, Songwriter Involved in Broadway Had a band in the 90s and early 2000s
These two individuals, Born three years apart, decided they wanted to be artists, and go by the nickname “Trey” despite it having nothing to do with their third generation name.
Interesting stuff!
I have no idea who the other Trey Parker is.
Also had no idea Trey’s name was Randolph. But I guess it makes sense if that’s his dad’s name too. Randy, since IIRC Stan and Kyle’s parents were named after Trey and Matt’s parents.
