I want to try:

So the u-tube manometer was widely used in nazi-germany to measure the pressure of gases.

Clearly this is the origin for the namegiving of the video-plattform Youtube (you might have heard of).

Every single user of Youtube is a nazi.

The evidence is right there!!

Wake up sheeple!!

btw: this is meant to be sarcasm. Apparently this needs to be said nowadays.
