A pun does not commonly justify a blow in return. But if a blow were given for such cause, and death ensued, the jury would be judges both of the facts and of the pun, and might, if the latter were of an aggravated character, return a verdict of justifiable homicide. Oliver Wendell Holmes, Sr.
Some global hazards are insidious. They stem from pressure on energy supplies, food, water and other natural resources. And they will be aggravated as the population rises to a projected nine billion by mid-century, and by the effects of climate change. An 'ecological shock' could irreversibly degrade our environment. Martin Rees
A ghost is someone who hasn't made it - in other words, who died, and they don't know they're dead. So they keep walking around and thinking that you're inhabiting their - let's say, their domain. So they're aggravated with you. Sylvia Browne
