Question

what trick did Jacky play on jenny 4th class​

Answer 1

Answer:

The trick is that the first person did something surreptitiously, usually at the end of the "Johnny" sequence, such as folding their arms, putting their hands together, or saying "Now, you try." When the other people in the group try to repeat the "Johnny, Johnny" sequence, then, they are told they did it incorrectly.
