Olie-O's

My 3-year-old, in true Beevis and Butthead fashiong, likes to refer to her butt as her bung-holie-o, as adapted from corn-holie-o. Like "MOMMY, COME WIPE MY BUM-HOLIE-O."
Tonight it was, "Mommy, what is at the very tippy top of my nose-holie-o?"
"Your brain, sweetie."
"So if I stuck something small up there would it be lost in my brain forever?"
"Uhh, yeah."
"But my finger's not too small!"
