cue the crickets
1. A description of a quiet and sudden pause or lull in a conversation, following an inappropriate, embarrassing or really dumb comment, or comment on a subject no one cares about. Derived from a quiet setting ("cued" on a Hollywood or TV set), where the only sound is that of crickets in the background.
So did anyone catch that Paris Hilton post-jail interview?
