I must admit that I had seen that movie a long time ago and
it was a comic relief situation. Ford was visibly just
exhausted and did the only thing that was LOGICAL for him
to do in that instance. (I clicked in here thinking I was
going to be shown Easy Jiu-Jitsu. Indiana Jones probably
set the Jihadi movement back for several years after that
movie came out.)
I remember the movie scene, it produced quite a laugh from the audience.
