Tongue Twisters:

Two Truckee truckers truculently trucking to have truck to truck two trucks of truck.

Theophiles Thistle, the successful thistle-sifter,
in sifting a sieve full of un-sifted thistles,
thrust three thousand thistles through the thick of his thumb.
Now.....if Theophiles Thistle, the successful thistle-sifter,
in sifting a sieve full of un-sifted thistles,
thrust three thousand thistles through the thick of his thumb,
see that thou, in sifting a sieve full of un-sifted thistles,
thrust not three thousand thistles through the thick of thy thumb.
Success to the successful thistle-sifter!

Suddenly swerving, seven small swans
Swam silently southward,
Seeing six swift sailboats
Sailing sedately seaward.
