Can anyone help me with this quote?

[J.R.]

I was listening to this CD I just got by the Voo Doo Glow Skulls (an awesome latino-tinged ska/punk group, very cool) and it has a song entitled Shoot The Moon. The song opens with a deep, Leslie Nielson sort of voice saying "All right. men, it's time to shoot the moon!" I know I've heard this in a cheesy old sci-fi flick before, but i can't place it. Does anyone have a clue?
