King Kai: It’s…. It’s over.
Yamcha: What?
King Kai: Goku could not escape the explosion. Namek is gone, and so is he.
Yamcha: No. Goku no. NOOOOOOOOO! [Cries]
Tien: Why do you care?
Yamcha: Ah, wha?
Tien: Why do any of you care? Are you forgetting the whole reason they went to Namek in the first place? Now we have two sets of Dragon Balls.
Yamcha: Well…. yeah but you make it sound like death has no consequence.
Tien: It really doesn’t. We’re literally waiting to go back. Hell, this is Chiaotzu’s second time.
Chiaotzu: Next time I get a free sundae!
Yamcha: Huh.
King Kai: Huh.
Tien: Yeah.

DBZ Abridged on the lack of consequence concerning death in the series. Tien's supposed to be the only serious character in the series. That's the joke.

Edit: Perhaps I should explain this quote... I simply thought that Yamcha served as a good representation of most people's reactions... and Tien as a representation of "Um. It's no biggie." The rest of this series finale went off without a hitch as all characters realized "Wait. There are almost no consequences here. There may never be? What's the use in grieving!"
