When you know you are not dealing with a mopar person

Worked for a guy many years ago that swore his neighbor had an original 383 hemi super bee with a Muncy 4 speed. Asked him if it had a 6pack, too. LOL. He looked at me like I had 2 heads and informed me the hemi only came with a 4 barrel....... he couldn't even tell I was messing with him.
And it's those types that stubbornly stick to their story.

No, can't man-up and admit you're wrong. That would be the end of the world.
