What did James Caan's character mean where...
... in a scene where that man pointed a gun at him in that lab and he twisted his arm to hold him at gunpoint in return and he says "Some people take stuff for grunted, like the ability to chew solid food" - how was that in any way related to him confronting that guy with a gun in a lab and also him hunting Arnie's character?
And did he mean that guy with a gun when he said "take stuff for grunted" or Arnie?
Thanks.
