No Inigo, I’ll take the blame. :smack:
Anyway, I believe his first John Wayne imitation occurs in the first barracks scene where R Lee Ermey is “introducing” the new recruits to the Marines. Private Joker mumbles his John Wayne imitation and R Lee Ermey gets pissed and wants to know who said that.
I don’t think that really helps the OP but at least we know where the John Wayne references begin.
