English can be fun too

Bad grammar
"Is this a picture of you?"
"Yes. That's me?"
"That's bad grammar."
"I know it. It's a bad picture, too."

"Your narrative is too high coloured," remarked the editor, returning the bulky manuscript.
"In what way?" inquired the disappointed author.
"Why," replied the editor, "in the very first chapter you make the old man turn purple with rage, the villain turn green with envy, the hero turn white with anger, the heroine turn red with blushes, and the detective turn blue with cold."

"Can you tell me the difference between valour and discretion?
"Well, leaving a swank weekend party without tipping the servants would be valour."
"And discretion?"
"Not going there again."

He: No, he couldn't even entertain a doubt."
