I want all three to be true!

So, number one...This is definitely legit as I can imagine this happening for sure. Number two....Hmm, I can imagine that smirk of Nicholson's and a flippant salute as he drove by uncaring of your plight...Number three...Hmm...Could be legit, but I'm going to call it out as bullshit! (you sure there was no deliverance-style action?) Lol

Bonus round:

That stick was totally thrown at you like a javelin, probably by Jack Nicholson too!
