Stopped at a car show tonight.

Here is my car show night mare story. I'm sitting in my lawn chair beside the fish smokin a cigar and sipping on a grog, when this older gentleman walks up and says "what year?", "68", "you sure?", "yup", "no I think its a 65, my buddy had one", no I'm pretty sure its a 68, you see its my car", "I don't know, looks like a 65 to me" "No its a 68, you see they didn't make a 340s or a notchback in 65 and if you look at the car beside me, the one that says 65 on it?, thats a 65 Barracuda" So he takes a look and reluctantly agrees with me, then comes back and says "my buddy had a 19 something or other with a 426 hemi in it", I said "oh ya, the good old elephant"... "no they never called it that", oh boy here we go again, I called my pal over who knows every mopar motor ever made and he proceeded to give this guy a lesson.
Generally I don't mind the questions or stupid comments but this guy was a real dip.
You should have seen the time some kids were bouncing on the wheelie wheels of my buddies pro street vega, with the parents standing there watching, when he snapped the parents got mad at him! ...what the ....?
