Tongue Twister Quote: Now.....if Theophiles Thistle, the successful thistle-sifter...

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.
