The ep about the man who travels back in time to 1881. Here is what they disliked. The traveller, Paul Driscoll, knows exactly when Garfield is to be assasinated. The online poster thought it idiotic that Driscoll would know right off the top of his head exactly when Garfield would be shot.

PS Drinscoll mentions ( while in 1881) Inchon referring to the Korean War. See my Mash TV postings on here.
