Another Question About Gravity on the Moon

This is a link to the famous golf shot by Alan Shepard on the moon. At 1:42 into the video clip, after his first unsuccessful attempt to hit a golf ball with one hand, he takes a pathetic swing at a second golfball and says, "Miles, and miles, and miles," after the swing.

Why did he say that?

Did the golfball travel for miles and miles and miles or was he just being sarcastic? If you look close enough you can clearly see the ball dribbling out a few feet in front of him. Maybe he was just joking? When we were kids we were told that since the moon had 1/6 the gravity of earth that the golfball would fly for a great distance hence the comment, "Miles, and miles, and miles."

Also notice when he drops the golfballs onto the surface of the moon they fall like, well, they fall like golfballs falling on earth. Why do golfballs fall like rocks to the surface of the moon, yet when the astronauts walk they bounce around like they are suffering from weightlessness?
