xkcd

I'm driving. I lose my brakes and can't slow down as if my gas pedal is stuck (unstoppable force). I'm on a road that stops at a T intersection and there's a concrete wall to keep people from going straight when they are moving vertically towards the T intersection (immovable object).

The car just goes right through the concrete wall with no damage?

Replace the concrete wall with a wooden fence. Technically the fence is immovable, but the car is going to smash right through that thing.

So is this about clarifying what exactly the objects are? I'm not smart enough for this one and am so confused...
