I love the idea of fun little challenges like these, especially the beach ball one. If only they could release mini-missions like these.

By the way, have you played Half-Life 2: Episode Two? Because there's this achievement for carrying a garden gnome across the entire game, which reminds me of the Beach Ball challenge.
