It doesn't take too long...but before too-long the come-backs come quick.
They are best when they are "off-the-wall" with a double-entendre meaning....one which the audience is quick to pick-up on...and laugh....and the loud-mouth is left stunned....not sure what the audience is laughing at....and fearing it might be them.
Hell, Sorcha if we ALL played convalescent hospitals, police-balls, and elementry schools.....there would be no need for gorilla tactics in the urban jungle.
SINcerely,
