The Italian Cruise: Venetian Love Song/Down for the Count/Arrividerci, Gopher/The Arrangement: Part 1
The Love Boat
When the crew arrives at the port of Civitavecchia by taxi, they admire the ship from the dock and Gopher has his hands bandaged. When the shot changes to show the crew walking toward the ship, Gopher (or a stand-in for the actor) does not have bandaged hands.
Gopher's kidnapper takes his clothes and even makes a point of showing that he took his gloves so as to pass himself off as Gopher. But when Gopher escapes, he is also wearing the gloves. There is no reason to think that he went ashore with two pairs of gloves.
