Watch Laura Daniels Try the World’s Toughest Tongue Twister

"Pad kid poured curd pulled cod."

Researchers -- yes, actual researchers spent time on this -- at Massachusetts Institute of Technology (MIT) have deemed this sentence as the world's hardest tongue twister.

MIT psychologists tried to determine if they could induce "double sound mistakes" (like "c" and "t") with different tongue twisters, and recorded volunteers saying a simple list of words, along with full sentences.

Researchers said there were two reactions when people tried the sentence:  they either failed to repeat it, or they stopped talking altogether (???).

Try it 10 times fast for yourself.

I'll wait.
