While all previous translations were objectively shit (my errata in Hungarian about What If? is here: https://gist.github.com/v-p-b/32acda745cf3bfc4713c0d9144e60ce6 ), it's a new low that the Hungarian publisher even managed to mistranslate the subheading of XKCD's How To?:
The original is "Absurd Scientific Advice for Common Real-World Problems", while the translated version says "Serious Scientific Advice". The two words are not even related in Hungarian.
