Klingons say, "Today is a good day to die."

Jem'Hadar say, "Victory is life."

Good titles for pretty much any future show:
"Hail, Hail, the Gang's All Here"
"Death Among the Stars"
"Far, Far Away"
"Nomad"
"Proud Romulus"
"Web of Deception"
"Smoke and Mirrors"
"Empire of Ages"
"The Demolished Man"
