Halloween Brings Them ALL Out!

Little guy, a couple of aisles over from me at Walmart, kept singing out.
"Buttmaaaaaaan! Buttmaaaaaaaan!" But then, it IS Halloween, so maybe I should have checked to see if he was wearing a superhero costume. Perhaps Alfred was pushing him & Robin in the cart. However, I didn't hear the Butt-Phone ringing or notice any Butt-Signal shining in the sky.
