Celebrity: Tom Selleck
Second job: Avocado farmer
The deets: When not portraying solid, respectable policemen on TV, Selleck has a second job in tending to his 60-acre avocado farm, where working the land serves as his form of exercise. With more than 2,000 avocado trees on his property, Selleck has been a successful avocado provider -- despite the fact he's admitted distaste for eating the fruit himself. He has had setbacks, like all farmers, including having more than 600 trees killed in a 2007 frost. But in the past few years, Selleck has had another potential challenge, of sorts -- a celebrity rival in Jamie Foxx, who also has a second job growing his own avocados on the other side of their shared fence.
