He hadn't known what had possessed him to ask the Doctor to take him back to the day he was born. He hadn't witnessed the actual birth, but he had stopped by to congratulate his mother and have a look at himself. All 8 pounds 2 ounces of him. Though he'd wanted to do more, probably say something to his mother that would make her stay, he found that he couldn't handle things and had to leave.

Since the Doctor had given him an hour and had wandered off somewhere with Rose, he had found himself wandering aimlessly near Maternity. Eventually, he found himself where the documents were being typed up in order to be sent to Records.

"...And then, we're going to go to Disney World..." the woman who was typing up his and his parents' information said, talking about her upcoming holiday in America as she typed his name.

As he watched her type, he looked down at the handwritten information that had been supplied by his parents and the attending physician, and then back up at what the woman had just typed for his official records and back down again. It was blatantly obvious that something didn't match, and that the mistake had been on the typist's part.
