The try harder if ye want to keep a second joke thread thread

Can’t believe what I saw in McDonald’s today. An old man placed an order for one hamburger , French fries and a drink.
He unwrapped the plain hamburger and carefully cut it in half , placing one half in front of his wife.
He then carefully counted out the French fries , dividing them into two piles and neatly placed one pile in front of his wife.
He took a sip of the drink , his wife took a sip and then set the cup down between them. As he began to eat his few bites of hamburger , the people around them were looking over and whispering.
Obviously they were thinking , 'That poor old couple - all they can afford is one meal for the two of them.'
As the man began to eat his fries a young man came to the table and politely offered to buy another meal for the old couple. The old man said , they were just fine - they were used to sharing everything..
People closer to the table noticed the little old lady hadn't eaten a bite. She sat there watching her husband eat and occasionally taking turns sipping the drink.
Again , the young man came over and begged them to let him buy another meal for them. This time the old woman said 'No , thank you , we are used to sharing everything.'
Finally , as the old man finished and was wiping his face neatly with the napkin , the young man again came over to the little old lady who had yet to eat a single bite of food and asked 'What is it you are waiting for?'
She answered
'THE TEETH'.
