Can anyone help me make some tongue twisters even more convoluted and difficult?

Question

Here's what I've done to one classic to make it more difficult:

Peter Piper picked a peck of prickly purple pickled peppers;
A peck of prickly purple pickled peppers Peter Piper picked;
If Peter Piper picked a peck of prickly purple pickled peppers,
Where's the peck of prickly purple pickled peppers Peter Piper picked?

Anyone care to take this further?

Also, I havn't thought of anything for the tongue twister "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 as a woodchuck would
If a woodchuck could chuck wood."

nor

"A skunk sat on a stump. The stump thunk the skunk stunk. but the skunk thunk the stump stunk . What stunk the skunk or the stump?"

Can anyone take and expand these ad nauseam?

Answer 1

Here are some more.. try them..

I'm not the pheasant plucker, I'm the pheasant plucker's mate,
And I'm only plucking pheasants 'cause the pheasant plucker's late.
I'm not the pheasant plucker, I'm the pheasant plucker's son,
And I'm only plucking pheasants till the pheasant pluckers come.



Another English tongue twister:

Betty Botter bought some butter, "But", she said "this butter's bitter, If I put it in my batter, it will make my batter bitter! But a bit of better butter will make my batter better!". So she bought some better butter, better than the bitter butter, and she put it in her batter and her batter was not bitter! So 'twas better Betty Botter bought a bit of better butter.



And another:

Theophilus Thistle, the successful thistle sifter, in sifting thousands of unsifted thistles, thrust thrice three thousand thistles through the thick of his thumb.



This one won grand prize in a contest in Games Magazine in 1979:

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