HS: Sir, is this your bag?
HS: What's in it?
Me: A cow bone.
HS: What is that, like a vase or something?
Me: No, it's literally the bone of a cow.
HS: (Face goes blank. Pauses for two seconds. Starts to walk my bag to the bag-search crew. Three steps in, pauses again, laughs, turns back to me.) Okay, you can have it.
HS: (Under his breath, as I'm walking away.) "Literally the bone of a cow." (Chuckles.)
