Mushroom With One Bite Missing: NOPE!

I was in the Barrens on this morning, and the damp summer woods are full of fungi. I came across this mushroom with a single bite out of it, and I was intrigued by it. And amused. (Okay, so I'm pretty easily amused.)

It looks like that'll be a great big NOPE!

Now, did that one bite make somebody nine inches tall? 
Or did it make somebody taller than the treetops?
We'll never know!

I couldn't decide between these two songs for my soundtrack, so here they both are! Tom Petty and the Heartbreakers, with Don't Come Around Here No More; and Jefferson Airplane, with White Rabbit.
