A guy driving on a parkway on Long Island saw this tractor trailer driving in front of him, knowing that trucks are not supposed to drive on parkways because — as that scene on the first episode of Louie has now taught us — the overpasses are too low to pass under. As such, he got his camera ready knowing some sh*t was about to go down, which it almost immediately did after he started filming.
According to the YouTube description, the drive was visibly upset (as he damn well should be) but for the most part unharmed. Which, in my book, makes it perfectly acceptable to make fun of the gigantic dick-for-brains who crashed his truck into an overpass.
