Great tongue twisters

Pinky and the Brain take it to a whole new level!

Shep Schwab Shopping

"Shep Schwab shopped at Schwab's Schnapps shop;
One shot of Scott's Schnapps stopped Schwab's watch."

The Pheasant Plucker's Son

I'm not the pheasant plucker
I'm the pheasant pluckers' son
I'm only plucking pheasants
Til the pheasant plucker comes.

Shoe Shine Susie

I saw Susie sitting in a shoe shine shop.
Where she sits she shines, and where she shines she sits. 

The Tree Toad

A tree toad loved a she-toad
Who lived up in a tree.
He was a two-toed tree toad
But a three-toed toad was she.
The two-toed tree toad tried to win
The three-toed she-toad's heart,
For the two-toed tree toad loved the ground
That the three-toed tree toad trod.
But the two-toed tree toad tried in vain.
He couldn't please her whim.
From her tree toad bower
With her three-toed power
The she-toad vetoed him.

How Much Wood

How much wood
Would a woodchuck chuck
If a woodchuck could chuck wood?
He'd chuck all the wood
That a woodchuck could
If a woodchuck could chuck wood.

Betty Botter's Butter

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.

Tooting Tutor

A tutor who tooted the flute
Tried to tutor two tooters to toot
Said the two to the tutor
"Is it tougher to toot
Or to tutor two tooters to toot?"

Silly Sally

Silly Sally swiftly shooed seven silly sheep.
The seven silly sheep Silly Sally shooed
Shilly-shallied south.
These sheep shouldn't sleep in a shack;
Sheep should sleep in a shed.

Three Sweet Switched Swiss Witches

Three sweet switched Swiss witches
Watch three washed Swiss witch Swatch watch switches.
Which sweet switched Swiss witch watches
Which washed Swiss witch Swatch watch switch?

Theophilus Thadeus Thistledown

Theophilus Thadeus Thistledown,
The successful thistle-sifter,
While sifting a sieve-full of unsifted thistles,
Thrust three thousand thistles through the thick of his thumb.

Now, if Theophilus Thadeus Thistledown,
The successful thistle-sifter,
Thrust three thousand thistles through the thick of his thumb,
See that thou, while sifting a sieve-full of unsifted thistles,
Thrust not three thousand thistles through the thick of thy thumb.

Peter Piper

Peter Piper picked a peck of peckled peppers, a peck of pickled peppers Peter Piper picked, if Peter Piper picked a peck of peckled peppers, where's the peck of pickled peppers Peter Piper picked?

Doctor

When a doctor gets sick and another doctor doctors him,

Does the doctor doing the doctoring have to doctor the doctor the way the doctor being doctored wants to be doctored,

Or does the doctor doing the doctoring of the doctor doctor the doctor as he wants to do the doctoring?
