Just a note, but the initial comments and method name seem to be for some other kata? (In ruby, at least! They said something about ages?)

My code passed all the provided tests, up until the random tests, in which every one not expecting nil was failed. However, all of the non-nil random tests also expected "way" to be added to the end of all output, even at the end of random strings that did not begin with vowels. This would seem to be an error?
input: schUB
Expected: "ubschayway", instead got: "ubschay"
EDIT: Oddly enough, copy/pasting a working solution seems to fix the problem with the expected output, in that it no longer expected all random words to end in "way". So... Is this somehow a problem with my code affecting the parameters of the Kata...?

Wasn't this on the Euler problem database, or something very similar?

When I run what code I have through the submit button, it passes the normal tests, but fails every single one ofthe random tests. From what I can tell, the random tests seem to be considering the right answer to be the same string as the input i'm given! For context, here's one of the messages I'm getting from the random tests section (In ruby, if it's any help?)
Testing for mCklt84;Yda y; #I"m assuming that this is the input here?
Expected: "mCklt84;Yda y;", instead got: "nXpog84;Bwz b;" #And here, the expected result is the same as the input!
I'm probably reading things wrong, but help would still be really appreciated, as this has happened on a few other katas I've tried.
