Broadway/Touring Shows that I've Seen: Peter Pan, The Lion King, Wicked (twice), Avenue Q, Young Frankenstein, Les Miserables, Shrek the Musical, The Producers, The Book of Mormon (twice), Matilda, Once, and Kinky Boots.
I didn't see it AT ALL upon the first viewing. After a few minutes I came back to look again, and it did pop out at me. It kind of a stretch, I doubt it was on purpose, but who knows? You have an active imagination, though! Good eye, lol!
