I Can Has Humanz

(A coworker and I are at the customer service desk when a lady with a newborn baby comes in.)

Coworker and I: “Aww, what a cute baby!”

Lady: “Thanks!”

Me: “How old is he?”

Lady: “He is 13 days old.”

Coworker: “Has he opened his eyes yet?”

(The lady and I exchange glances and start laughing.)

Coworker: “What’s so funny?”

Me: “This is a baby, not a cat. They open their eyes at birth.”

Coworker: *dumbstruck* “Really?!”
