The Adventures of Rocky and Bullwinkle and Friends, Season 1

Narrator:
And if that weren't bad enough, when the boys were on their way home, the two spies, Boris and Natasha, received their latest instructions.

Boris:
Don't tell me. Let me guess. I'll bet it says, "Keel Moose", right?

Natasha:
[reading the secret instructions as they are revealed] Right.

Boris:
Okay!

[Boris cuts a rope, dropping a safe out a hotel window toward an unsuspecting Bullwinkle and Rocky below]

Natasha:
... But in front are two more words: "Do Not".

Boris:
[reading the full message] "Do Not Keel Moose"... Oh, Boris, you impetuous boy. What have you done?

Natasha:
Better yet, what will you do?

Boris:
Save him! I've got to save him!

[Boris rushes down several flights of stairs as the safe continues to fall]

Narrator:
Boris raced to beat the heavy safe to the ground, and he won!

[the safe lands on top of Boris just outside the hotel entrance, driving him into the ground with a crash]

Narrator:
... Almost. The heavy safe drove him into the ground like a tent stake! Bullwinkle's keen mind knew instantly what had happened.

Bullwinkle:
Hey, up there! You dropped your safe!
