Once upon a time, Harry Potter was about to turn seventeen. He knew that the second the clock struck midnight, Voldemort and his Death Eaters would arrive to capture him. He also found out that a corrupt Ministry of Magic official had made it an imprisonable offence for him to use Floo powder, portkeys, or Apparition to escape.
All seemed hopeless, and Harry thought he would have no choice but to let six of his friends use Polyjuice potion and pretend to be him. With these seven Harry Potters, the Death Eaters wouldn’t know which Harry was which when they made their daring escape — although this would also put his friends in great danger, and might very well end in their death and/or dismemberment.
Then Harry remembered that he wasn’t a complete idiot, and that he didn’t care about being imprisoned since the Ministry was already under Voldemort’s thumb. So he told Moody and the Order of the Phoenix to call off their ridiculous plan, and he waited more-or-less peacefully in the Dursley’s house right up until his birthday.
At three seconds to midnight, he Apparated to some random field in the middle of nowhere. He knew that the Death Eaters would follow him, but he wasn’t worried, because he remembered that he wasn’t playing an online game, and that the Apparate spell doesn’t have a cooldown.
So Harry immediately Apparated again — straight to the Burrow, this time — and the Death Eaters had no idea where he went because by then it was past midnight, he was now seventeen, and the trace spell that the Ministry used on him to track his underage magic usage had stopped working.
Harry Potter therefore arrived safe and sound at the Burrow without putting any of his friends in danger, or getting anyone’s ear blown off, and everyone was very happy to see him and they all ate treacle tart to celebrate.
