Louis: {after a long period of puzzled silence} You know when you look down the barrel of inertia?
Me: No, but that's very profound Louis.
Louis: What does profound mean?
Nic: Profound is when you think about something very hard and then say something wise...
Louis: Oh
Nic: ...and 'staring down the barrel of inertia' is a very profound thought Louis.
Louis: No, I said 'you know when you look down the barrel of a nerf gun'
