If you don't consider y's vowels, there are many possibilities (Think of the puzzle in the 7th guest where you had to make a sentence out of letters where you were given no vowels). Shy gypsy, shyly, spryly tryst by my crypt.
also, syzygy.
and many others, I'm sure.

But why would you not consider any y's to be vowels? The rule is "sometimes y (and w)", not "y if you feel like it". Y is a vowel when it makes a vowel sound as in crypt, by, syzygy, rhythm, happy, gray, etc., and it is a consonant when it makes the "yuh" consonant sound, as in yellow, you, and yuppie.

So if you exclude the words with W in them (and possibly add the dubious words TSKTSK and TSKTSKS), medwyn's list does in fact contain the only words without vowels.
