The old man unwrapped the hamburger and carefully cut it in half. He placed one half in front of his wife, He then counted out the french fries and gave half to his wife. He then took a sip of the drink and placed it between them.
The people around them whispered that poor couple can only afford one meal between them.
As the man took a bite of his hamburger a young man came across and politely offered to buy another meal for them but the old man refused saying they were used to sharing everything.
The young man noticed the old lady hadn't eaten a bite.Again the young man offered them another meal this time the old lady refused saying they were used to sharing everything.
As the old man finished his meal and was wiping his face the young man noticed the old lady had not eaten a thing and he asked "what are you waiting for"
she answered
"THE TEETH"
