5 or more people are sitting on a bench with their right leg crossed. The person at the end of the bench says to the person beside him "Is it time yet?"
That person says the same to the next person, who says it to the next person until the messeage gets to the last person on the other side of the bench.
That person checks his/her watch and says "No" to the person beside him and then that person says it to the next person until it gets to the last person.
Repeat 2 more times and then 1 more time but instead of the person saying no the person says "Yes!" and evryone switches over there legs!
