I would have loved to hear that phone call.
I had someone attempt to do that to me on the freeway in Kansas City, but I had just watched a video on it, so I knew what was coming.
Typical big truck riding my bumper, he passes (4 lanes each way) and gets in front of me, then slows down. I had already dropped it into 3rd at 50 and as soon as I felt the moment was right, I let the clutch out and dropped the hammer.

Passed him just as the soot was starting to come out and saw a big cloud in my rear view. I proceeded to get in front of him, slow down to 50 (70 zone), and not let him pass again. He was sooooo pissed!

Shaking his fist, giving me the finger, yelling...all the while I'm laughing my a** off and smiling at him in the rear view.
Sorry for the bad grammar and irresponsible behaviour.
Jake: don't drive that way! Do as I say, not as I do!
