By Sarah McBride SAN FRANCISCO (Reuters) – Shortly after moving to Silicon Valley in 2004, the young Facebook founder Mark Zuckerberg pulled a prank on Sequoia Capital by making an investment pitch in his pajamas. The discussion never got serious, and Sequoia never invested in Facebook. But now, Sequoia is getting the last laugh. With the sale of its protégé company message service WhatsApp to Zuckerbergs Facebook for $19 billion, Sequoia found a way to make money from Facebook as well as solidifying its position as a titan of venture capital.
