Crack a joke: (v) to make a joke or say something humorous,
Throughout my years of travel, the most danger I ever placed myself in always revolved around cracking a joke.
There are people on this Earth who consider such a response to be ill-founded, immature and sometimes irreverent.
I know there are many tests given to determine mental health, but I will guarantee you—the litmus assessment of good brain function and emotional soundness of being is whether you come across a very delicate, serious situation and decide to embrace it in a somber manner or to find something funny within.
The world ultimately will not be saved by those who crack the whip or even those who crack a smile.
We are desperately in search of those who can crack a joke at just the right time to change our thinking from doom and gloom to glee and whoopee.
