Tongue Twisters

My friend and I were eating lunch in the tearoom and our conversation got around to tongue twisters.

The most common ones :

She sells sea shells by the sea shore.
The shells she sells are surely seashells.
So if she sells shells on the seashore,
I'm sure she sells seashore shells.

How much wood would a woodchuck chuck
if a woodchuck could chuck wood?
He would chuck, he would, as much as he could,
and chuck as much wood as a woodchuck would
if a woodchuck could chuck wood.

Betty Botter had some butter,
"But," she said, "this butter's bitter.
If I bake this bitter butter,
it would make my batter bitter.
But a bit of better butter--
that would make my batter better."

So she bought a bit of butter,
better than her bitter butter,
and she baked it in her batter,
and the batter was not bitter.
So 'twas better Betty Botter
bought a bit of better butter.

My personal favourites and I think they are damn difficult to say it fast! I tried and tried but my tongue would not cooperate with me on this! They are simple phrases, mostly one liners but man, watch out!

Six thick thistle sticks. Six thick thistles stick

The sixth sick sheik's sixth sheep's sick.

Which witch wished which wicked wish?

Chop shops stock chops.

Selfish shellfish.

A bloke's back bike brake block broke.

And these are in Japanese :

Kaeru pyoko-pyoko

awasete pyoko-pyoko mu pyoko-pyoko.
