               Alright, this is driving me crazy... I figured all the syllables, except the close up of the winking face in the third one...
It spells out infinity, so it's either ni, nit or it... but I can't figure out what it is...

               It's "inn" "fin" "eye" "tea".  I realize it's a stretch, but you asked the question and we have enough madmen here as it is, ZFR *lol*
