The Doctor and Mundy in “Boom”

I'm a much bigger bang than you bargained for. I'm a lot more explosive than I look, and, honey, I know how I look. Put a quantum chain reaction through me, and I will shatter this silly little battlefield of yours into dust. All of it, in a heartbeat, into dust.

That's not possible.

Everything is possible! Everything is possible. Everywhere is a beach eventually. Scan me! Scan me, see for yourself!

You could blow up half of this planet!
