I am TellAPhony and I make the RWBY Play-By-Play.
The username TellAPhony comes from an inside joke from the communications industry. Telephony is the “workings or the use of a telephone” and some people will try to pronounce it Tell-ah-phony, but veterans in the business will know the correct pronunciation Tell-eff-any.
The joke goes “You can always tell a phony when they say Tell-ah-phony.”
It’s not funny per-se, but it provides a convenient username.
