The guys who sell kitchen gadgets on street corners in New York and the boardwalks of New Jersey are the ultimate salespeople. I’ve run across several excellent profiles that study exactly how they sell and why they’re so successful.

• Malcom Gladwell’s 2000 profile of Ron Popeil
• Vanity Fair’s profile of Joseph Ades, the “Gentleman Grafter”

If you’re looking to get into sales, these guys are who you should learn from.
