There was a M*A*S*H reference on last night’s episode of Castle on ABC, which involved a bank robbery. The robbers were using code names, each of them being called Doctor [Something] and one went by Trapper John. Here’s the pertinent exchange:
Detective Kate Beckett: “So what’s your name?”
Bank Robber: “You can call me Trapper John.”
Detective Kate Beckett: “A MASH fan. That’s Nice.”
I have updated M*A*S*H References on Television with this latest reference.
