What part of I want a pony don't you understand?

When I was young, like most little girls, I guess I regularly asked my parents if I could have a pony. To slow my repeated questioning, one of my parents (probably my dad) answered me saying, "When you're age X*" *(fill in an age over 25).

This past weekend when celebrating my birthday with family my older brother gave me the card picutred here which has a caption that reads, "What part of, 'I want a pony.' don't you understand?"

Well, now my pouting can come to an end. ... See the post below....
