Genesis: Biblical Mean Mug

I think Laban should be credited with the first recorded mean mug in history.

And Jacob beheld the countenance of Laban, and, behold, it was not toward him as before.

—Genesis 31:2

This was hilarious to me. What kind of look did Laban have? Bear in mind that Jacob had bamboozled Laban out of some cattle, so I'm sure he wasn't happy. (I guess he forgot about how he did Jacob dirty concerning his daughters.)

In any event, I think the Bible makes it clear that at some point in time Laban began mean mugging Jacob, after which Jacob took it upon himself to secretly deuce out. Nothing good can follow from a mean mug.
