We can can vegetables, fruit and the Kaiser too
The pattern
This still is filed under Demonstration ad.
Define
The product does the arguing. The viewer sees the thing work, not a slogan about the thing working.
Mechanism
Proof by performance. The claim is the action: a visible, testable result the reader can replay.
Verdict
We can show a result in seconds
Why it works
Uses wordplay and dark humor to turn domestic food preservation into a literal act of war. The surreal image of the enemy leader canned in a jar makes the metaphor unforgettably literal.
Steal this when
When trying to mobilize a crowd by directly connecting a mundane supportive action to the defeat of a shared enemy.
