Walla! (somebody gag me...)

I've noticed a word massacre perpetrated by our southern friends of late. Everytime I hear it (or see it in print for that matter) I want to puke. It goes something like this:

The magician showed us the empty hat, and then Walla! He pulled a rabbit out of it!

Its a blatant corruption of the word Voila, which not only sounds more appealing, it also looks more aesthetically pleasing than Walla. Please do me a favour. If you hear someone say this abomination punch them in the face. The world will be a better place for it....

Incidentally I wonder if this corruption began around the time "french fries" gained the name of "freedom fries"...
