Noticed something on Smilin' Jack
The soldier wounded at the beginning of the episode asks BJ whether he's ever been at the front; BJ replies he's never had the pleasure of some such thing. I guess he forgot that on his way to the 4077th, he was targeted by artillery or mortars. After the attack, he turned over a soldier, saw what happened to the soldier and threw up.
I realize finding continuity errors in MASH is like shooting fish in a barrel, but it's still fun.
