Why is the Amazon boss in celebratory mood...
This competition is now closed, read the winning entry and the runners up below.
WINNER: "Yes! We only delivered the Christmas presents two weeks late this year..."
2nd: Bezos gets confirmation that the final Harry Potter book is coming out soon...
3rd: Jeff wins silicon.com's caption competition
Christian Sharp badly overestimates the scale of the bottles of bubbly we award the winner of this weekly competition.
4th: "It had better not be BOLly..."
Rob Falconer , who clearly remembers the days of the dot-com boom and one of Amazon's early rivals BOL.com (who are apparently still going and big in the Netherlands).
5th: Bezos over the moon, even if his spacecraft isn't.
Simon Coley rightly picks up on the fact the photo was from the party to celebrate the lift off of the Amazon boss's personal space craft.
