Is there a difference in the Gnd pins on an Arduino Duemilanove?

I am working on an Instructable where it instructs you to connect the Negative wires from two servos and a Ping sensor to Gnd. Can I connect all three to the same Gnd? Also, is there a difference between the two Gnds on an Arduino Duemilanove? Which Gnd should I connect them to?

The two grounds are the same thing, and yes, you can attach them all to the same ground.
