Okay I think I finally have it:
Its bee on words ("It's beyond words")
Or it could also be said:
Four its bee on words ("For it's beyond words")
Explanation
The first part is as everyone assumed it was along the lines of:
There are"It" is there 4 "it"stimes so its either "it's""it's" or "For it's.""For it's." I think the only difficulty was how it related to "BEE."
And the second part was tricky:
The word "Bee" is resting directly on a series of words that exemplify the different parts of speech, but don't make a sentence. We have "Cow""Cow" (a noun), "One""One" (which can be a number or a pronoun), "Run" "Run" (which can be a verb or a noun), and "As" "As" (which can be an adverb, preposition, or a conjunction). These words were likely chosen because, while being only 4 words, they cover the essential parts of speech that makecompose a sentence. So this part of the puzzle is probably just "words." When "Bee on words" is spoken loosely, it sounds like "beyond words" finishing--finishing the sentence.
Other possible variants could be:
"It's over beyond words" (the "It"s are over "Bee" but it's not a common quote), "It's far beyond words" (the "It"s aare far from the "Bee"), "It's simply beyond words" (there's a popular quote worded like this), or even "It's way beyond words" (the "it"s being a far from the other words.) And any of these could have "For""For" at the beginning, but the wording I would go with is just "It's beyond words" because it's the most common phrase of all the possible variants.
After days of chewing on it, that's the best I've come up with. I hope someone can verify whether or not it's the right answer or not on your Facebook.
