I was just a-looking at wiki pages on rhyming slang, then mock latin, where was I mightily tickled -
Caesar adsum jam forte....
Meself, also on the list of speech balloon possibilities, I had -
Nona dama nevit (dama = female deer... Hind)
Non ad Aman evit (Aman is a fictional place, Tolkien)
but these have Adam hiding, making Eve even harder to spot... altogether too difficult to decipher.
