It’s said that police sergeants in Leith, Scotland, used this tongue twister as a sobriety test:

The Leith police dismisseth us,
I’m thankful, sir, to say;
The Leith police dismisseth us,
They thought we sought to stay.
The Leith police dismisseth us,
We both sighed sighs apiece;
And the sigh that we sighed as we said goodbye
Was the size of the Leith police.

If you can’t say it, you’re drunk.
