One of our customers calls everytime when he thinks he found a new bug. Then he literally yells "I found a new bow" since he thinks "bug" is a german word, so emphasizes it like that. In german "bug" means "bow of a ship".

But "Bug" in german is spoken completely different. Sounds more like "Buuk" in German while the English "bug" is spoken like "baag".
Well... Anyways this doesn't even make sense.
Why should anyone call a computer error "Bug" (bow of a ship) ?
It's "bug" because an inexplicable error is similar to a bug sitting in your circuits.
