Sound advice from a co-worker of mine, Always have a joke up your sleeve and a smile on your face. My reply was a Knock Knock joke...... "Call and Answer" exercises was once a variation of children's game in 1920's. The game of Buff a child with a stick thumps it on the ground, and recite:
What says Buff?
Buff says Buff to all his men, And I say Buff to you again.
Probably similar to more of a game we call Simon says, but children games are often strange. This must have been one hell of a game since we are practicing knock knock jokes almost 100 years later. Brush up on your knock knock jokes while looking at door knockers.
Knock knock… Who’s there? A little old lady… A little old lady who? Oh! I didn’t know you could yodel.
