“Good Morning!" said Bilbo, and he meant it. The sun was shining, and the grass was very green. But Gandalf looked at him from under long bushy eyebrows that stuck out further than the brim of his shady hat.

"What do you mean?" he said. "Do you wish me a good morning, or mean that it is a good morning whether I want it or not; or that you feel good this morning; or that it is a morning to be good on?"

"All of them at once," said Bilbo. "And a very fine morning for a pipe of tobacco out of doors, into the bargain.

...

"Good morning!" he said at last. "We don't want any adventures here, thank you! You might try over The Hill or across The Water." By this he meant that the conversation was at an end.
"What a lot of things you do use Good morning for!" said Gandalf. "Now you mean that you want to get rid of me, and that it won't be good till I move off.”

“Hey,” Watney said over the radio, “I've got an idea.”
“Of course you do,” Lewis said. “What do you got?”
“I could find something sharp in here and poke a hole in the glove of my EVA suit. I could use the escaping air as a thruster and fly my way to you. The source of thrust would be on my arm, so I'd be able to direct it pretty easily.”
“How does he come up with this shit?” Martinez interjected.
“Hmm,” Lewis said. “Could you get 42 meters per second that way?”
“No idea,” Watney said.
“I can't see you having any control if you did that,” Lewis said. “You'd be eyeballing the intercept and using a thrust vector you can barely control.”
“I admit it's fatally dangerous,” Watney said. “But consider this: I'd get to fly around like Iron Man.”
“We'll keep working on ideas,” Lewis said.
“Iron Man, Commander. Iron Man.”
