Kai Winn mentions that she has consulted with an orb and been told nothing. During the Season 7 episode "Strange Bedfellows," she again fails to interface with an orb and admits that she feels nothing when the wormhole opens.
The Klingon opera Nog listens to is the same one which Worf was singing along to during "Looking for par'Mach in All the Wrong Places".
Goof: When Jake and Nog agree to complete Chief O'Brien's work for him, Nog says "I'll scan and you calibrate", however, he hands Jake the tricorder by mistake.
Jake (to Weyoun): The entire future of the galaxy may depend on us tracking down Willie Mays... and stopping him.
Quark: (handing Nog a list of auction items) Here, find something you like and make a bid with all that latinum you've got stashed under your bed.
Nog: (looking around nervously) Shhhh!
Quark: Oh Nog, you don't really keep it under your bed?!
Sisko: Two days ago, this station felt like a tomb. I'd never seen so many of my crew depressed at the same time. But for some reason, it now seems as though a new spirit has swept through the station. As if someone had opened a door and let a gust of fresh air blow through a musty old house. Why is this happening frankly is... a mystery to me. After all, nothing has really changed. The Dominion is still a threat, the Cardassians are still threatening to retake the station, and I can still see the clouds of war gathering on the horizon. So why do I sense this newfound sense of optimism in the air? But maybe I'm overthinking this. Maybe the real explanation is as simple as something my father taught me a long time ago: Even in the darkest moments, you can always find something that'll make you smile.
Nog: It's not my fault that your species decided to abandon currency-based economics in favor of some philosophy of self-enhancement.
Jake: Hey, watch it! There's nothing wrong with our philosophy. 'We work to better ourselves and the rest of humanity.'
Nog: What does that mean exactly?
Jake: It means... it means we don't need money!
