In Pieter Brueghel the Elder's "Construction of the Ministry of Linguistic Destandardisation" (1563), flunkies in sixteenth century Flemish attire try to convince a management big shot (bottom left) that delays are the result of deficient scaffolding technique.

......After the great deluge people travelled from the mountain of the East, where the ark had rested, and settled on a plain in the land of Shinar. There, they built a great city and tower, the top of which would reach unto Heaven. But the LORD was angered and thundered "Behold, the people is one, and they have all one language; and this they begin to do and now nothing will be restrained from them, which they have imagined to do" (Who the devil do they think they are? They're getting too big for their boots!).

Thereupon the LORD confounded the languages so workers on the tower would not understand each othereth and the project would fail. (That'll learn'em). And the variety of languages and the dispersion of humanity were regarded as a curse to all but translators and interpreters whose heyday was about to begin.

... and, ding-dong, pooh-pooh, uh-oh, ya-he-ho, ta-ta, watch-the-birdie and FOXP2 language gene nonsense mutation hypotheses notwithstanding, that's why foreigners speak funny.
