Here’s one possible “certificate” that fits your whimsical constraints:

**CERTIFICATE OF UNEMPLOYED THUNDER**

This certifies that

**UNEMPLOYED THUNDER**

having rendered no storms, rumbles, or associated atmospheric services,  
is hereby recognized as:

**OFFICIAL NOISE WITHOUT DUTY**

Signed this day by the  
BUREAU OF IDLE WEATHER  

☁️⚡☁️

If by “exactly four spoons of alphabet” you meant something more specific (e.g., a fixed character count, four distinct letters used in all words, or a visual/typographic constraint), clarify that rule and I’ll restructure the certificate to match it.
