The electric shock torture scene.
Judging by how much Mel Gibson's "Martin Riggs" character was screaming, how PAINFUL do you think it was?
And also, in real life, if this happened that way, after being shocked by Endo a couple of times, would he really have the strength to beat up Endo like that and then survive and rescue Murtaugh and his daughter?
Speaking of Murtaugh, how painful was the salt in the wound scene? Cause he was ALSO screaming like hell as a result?
Much as I hope never to find out I wonder...
