tongue twister that chorallaries say before concerts

What a to-do to die today at a minute or two to two,
A thing distinctly hard to say but harder still to do.
For they'll beat a tattoo at a quarter to two:
A rat-ta tat-tat ta tat-tat ta to-to.
And the dragon will come when he hears the drum
At a minute or two to two today, at a minute or two to two.

it's lewis carroll.
