1. Blonde Baby

Look at how light his hair was! Maybe the baby could be blonde, too...
2. Doing Charity Work

At age 18, he spent 10 weeks in Chile doing charity work. Yep, he's pretty perfect.
3. Playing Polo

Why don't we ever get to see him in awesome action shots like this anymore?!
4. Surfer Boy

Even royal college kids need spring break.
5. Young Love

Aww! Someday the royal baby will look back and think 'Man, my parents were pretty hot.'
6. Sharp-Dressed Man

Did you know that Wills had wildly messy hair from 2003-2005? Was Kate not influencing him at this time?
7. On the Fly

William received pilot training for the Royal Air Force.
8. Polo Player

We can't wait to see him train his little babe to wack things while riding a horse.
9. Most Valuable Speaker

He presented at the Football Association Respect and Fair Play Award Ceremony, which sounds like the most polite possible sports event.
10. Bearded Boy

Um, when did he have a beard?! Was this during the Kate break-up? He looks great!
11. Just Another Pilot

Here's an excellent reminder that William's last name is 'Wales,' as that's the land he presided over before he got married.
12. Lovely with Children

This comes as no great surprise, but of course he's wonderful with kids. He'll be just as adorable with his own.
13. The Day

Oh, maybe you've seen pics from this event before?
14. Olympic Joy

William and Kate were just another pair of spectators rooting for their home country during the Olympics. Their gift to the UK was a little lucky PDA.
15. Leaving the Hospital

The royal couple snapped this sweet pic as Kate was leaving the hospital after announcing her pregnancy.
16. Last Event as Pre-Parents

They attended Queen Elizabeth II's coronation anniversary celebration together. Next time we see them, they'll be mom and dad!
