False friends: familiar names which mean something very different elsewhere

Ok, there was a fun one in the Mueller thread just now…

Um…“childcare worker - childcare worker mistake”? Hmm, no,… “mother goat - mother goat injury”???

I can tell, from context, that it’s probably equivalent to what in my childhood we would have expressed as “Ner ner ni ner NERRRR!”. Without context? NFI.
