A couple was going over the expenses for their upcoming wedding. The groom-to-be says, "$6,800 for a dress that's only going to be worn ONCE? What's up with THAT?!"
"Who says it's only going to be worn once?" asked his fiancee.
"Oh? You're planning to get married again? Gee, thanks."
"That's not what I meant." she said.
A bit angrily, he responded with "You know you can't wear white the second time, anyway!"
Containing herself, she replied, "No, but I do plan to have a daughter. She'll wear it on her wedding day. And she'll have a daughter who will wear it on her wedding day. And her daughter will wear it on her wedding day. It will become a family heirloom."
"Ha!" he said. "I'll bet your mother never bought such an extravagant dress."
"Oh yeah? Well, she did too, smarty!" she said smugly.
"Yeah?" said he. "Then why don't you wear hers?"
She replied, "Who wants to get married in THAT old thing?"
