An elderly couple goes to Burger King, where they carefully split a burger and fries. A trucker takes pity on them and offers to buy the wife her own meal.
“It’s all right,” says the husband. “We share everything.”
A few minutes later, the trucker notices that the wife hasn’t taken a bite. “I really wouldn’t mind buying your wife her own meal,” he insists.
“She’ll eat,” the husband assures him. “We share everything.”
Unconvinced, the trucker implores the wife, “Why aren’t you eating?”
The wife snaps, “Because I’m waiting for the teeth!”
