Only can think of, that the sun is called moon at night.. but I meant even more obvious wrong ones that noone over 4 think is true, cause the moon thing might be thought by some up to 8yo..
Didnt know the vodka thing myself (and vaguely heard stuff about iron maiden and twinkie not being true, but if it would have been on a(nother) quiz I wouldnt have made a comment that they were wrong)
Especially the blood question is the most obvious, and it is at the beginning aswell (on purpose?) so it not like you only would realise it near the end..
though for a fun fact, look up horseshoe crab and its blood.
But seriously, bintang is the most popular beer in australia. (Btw I just found out a small beer is called a pony in australia haha) The spicy green paste has to be pesto. Cook discovered north america. And one should obviously never end a sentence with a swear word.
