Because 7 ate 9 !
There is a mother a daughter and a son. The son ran away and the mother and daughter go look for him. They stop looking for him and go to sleep. Why did they go to sleep?
A man in New York City has $10. He spends $6.50 on tulips, and $3 on burger and coke. He then gets on the subway which will take him 7 stops for 50 cents. But he is forced to get off of the subway just 5 stops away from where he began.
Why is this?
