18. Matthew McConaughey, Chicken Coop Cleaner
You'll likely find this shocking, but America's favorite golden-haired slacker stereotype did a lot of travelling in his youth. McConaughey lived in Australia for a while as an exchange student (and we were so sure he diligently kept his undivided attention on his studies).

When asked about his time cleaning up after our egg-bearing feathered friends, McConaughey said the most McConaughey thing possible: "Those types of trips are really ones that leave a lasting impression."
