I always find it funny/annoying when people complain about spoilers. I mean, come on, the show hasn't been on the air for what, more than a decade now? If you're coming into a forum like this, you're risking being "spoiled." It's not like we're talking about a program that's still airing new episodes. Come on now.
In any case, "Explorers" is worth it just for this one exchange between Sisko and Son:
Sisko: Hammock time!
I laugh every time, man. Every time.
