Counting Is Half The Fun

(My girlfriend and I are cuddling and sweet-talking after being intimate, and this happens:)

Girlfriend: “I’d say you were one in a million, but that’d mean there are 7000 of you. I’d say you’re one in a billion but that’d mean there’s seven of you, so you’re one in seven billion!”

Me: “Well you’re one in fourteen billion!”

Girlfriend: “Wait, doesn’t that mean I’m only a half then?”

Me: “Yup. I’m the other half!”
