The debil's in the details.

Tom is sitting on the couch in his robe (hanging open) and a pair of boxers with little devil faces on them. Tommy walks up and pokes one of the devils.
Tommy: "Base."
Me: to answer Tom's questioning look, "Face."
Tom: "It's a devil."
Tommy: "Debil."
Tom: "Yes."
Tommy: poking devil faces as he speaks, "Debil. Debil. Debil."
Tom: "Yep."
Tommy: poking one last time at a particularly poorly placed devil face, "Debil weiner."
Me: "Yes it is."
Tom scowls at me.  I laugh.
