Note the similarities between the phrase "tick and tack" as found in that version of the Wallflower rhyme that Flash Company posted and this brand name for a mouth freshner that shows up in a number of "Brick Wall Water Fall" rhymes:

"Wait, Come back.
I think you need a Tic Tac.
Not 1 Not 2 But the whole six-pack"

Is this just a coincidence?
