I learned this at the Actors’ Workshop. Although it was a Method acting school, the place was, after all, still in London, where diction matters. So it was not surprising that one of our teachers, an Englishman, dedication himself to the eradication of garbled enunciation, especially “amongst the Colonials”, dubbing himself The Mortal Enemy of the Lazy Tongue.
To the end of combating telltale Lazy Tongue tendencies, students were required to repeat this vacuous little doggerel, over and over, as quickly as was tongually possible.
I will transcribe it the way my ears originally heard it. But feel free to deliver it in whichever dialect you prefer.
As fast and as often as you can.
And work that tongue!
Betty Bohtuh boht some buttuh
But she said, “This buttuh’s bittuh
If I put it in my battuh
It will make my battuh bittuh
But a bit of bettuh buttuh
Bettuh than this bittuh buttuh
Will but make my bittuh battuh bettuh.
If your tongue needs a nap, you’ve performed it correctly.
