expect the expected

The Brawn is feeling philosophical as he gets ready for bed. 

"People always say to expect the unexpected. But that doesn't make any sense. It's impossible. That's the point. It's like jumping to the moon without clothes."

There's a short pause.

"Well, without shoes."

There's a longer pause as he tries to work through this metaphor.

"Rocket shoes. It's like jumping to the moon without rocket shoes."
