« A Dumb Blonde Oxymoron »

According to a fancy word dictionary...

An oxymoron "combines contradictory terms."

Such as "open secret" and "wholesome Kardashian."

So maybe dumb blonde is redundant, not an oxymoron.

Unless you're a dumb blonde and hence clearly confused.

Or as Britney Spears might say, "Oops."

But we must act naturally and tell more dumb blonde jokes.

In my unbiased opinion.
