Last Crusade is arguably more cartoony and campy in a lot of ways. There's the revolving fireplace and hidden staircase gags, the "Scottish Lord" disguise, the pen ink in the eye, Brody's sudden buffoonery, etc. and for all of the complaining people have for the raft stunt in TOD or the fridge in KOTCS, they give a free pass to equally unbelievable things like the plane in the tunnel, the centuries-old Grail Knight and the fact the prologue with Young Indy shows him getting the fedora, whip (and knowledge how to use it), chin scar, fear of snakes and love of adventure all in the same afternoon. And let's not forget how he escapes from a moving train using a magic box he presumably had no clue how to use before.
