Parking lot @$$whoopin?!

I just saw this movie and browsed this forum, yet no one mentioned:

Good ol' Lyla (that's what I'm calling her) whooping the crap out of JT and Wheeler?!?! How unexpected was that? It was awesome! That was my "bwahahaha" out loud moment for the movie, I was kind of stunned they wrote that bit of comedy in there (although I know why, to show how twisted the boys became). It just seemed out of left field! Never mess with a country gal.

However, I find it hard to believe anyone could take a blow to the head with a tire iron as hard as they depicted it and not be knocked silly, but I'm not going to nerd out and nitpick. Just thought it was funny and wanted to mention it!
