What CATS from Zero Wing did to the ship in A.D. 2101, when war was beginning. Maybe it means "Somebody has set up a bomb on us?" No one will ever know for sure.
Famous line from famously remembered badly translated japanese video game Zero Wing, turned internet phenomenon with many different parodies of the original sega game
Narrator: In A.D. 2101, war was beginning.
Captain: What happen ?
Mechanic: Somebody set up us the bomb.
(spoken in the Flash animation as Someone set up us the bomb)
Operator: We get signal.
Captain: What !
Operator: Main screen turn on.
Captain: It's you !!
CATS: How are you gentlemen !!
CATS: All your base are belong to us.
CATS: You are on the way to destruction.
Captain: What you say !!
CATS: You have no chance to survive make your time.
CATS: Ha Ha Ha Ha ....
A poor Japanese-to-English translation in the 1991 Genesisgame Zero Wing, which is also famous for the origin of "all your base..."
It is commonly incorrectly stated as "somebody set us up the bomb". Clearly, the up comes before the us, although the resulting diphthongs makes it more difficult to say.
