"Riddle Me This!"

I've checked music, maths, astrology, astronomy, alchemy, umpteen codes, puzzles galore, Braille, geometry, biology, physics, chemistry, foreign languages, religions and symbols from the Aztecs to Zoroastrians, and all the modern signs and symbols too.

I search no more! I'm done! It's beaten me. Bwaaaahhhh!!!! :

I shall return to my book..."Lobotomy for Beginners".
