Mister Mxyzptlk

I've been mispronouncing his name wrong all along. I'm not sure why I thought it was "mix-ll-plix". Thanks to the internet I now know it's pronounced "/mɪksˈjɛzpɪtlɪk/ US dict: mĭks·yĕz′·pĭt·lĭk or /mɪksˈjɛzpɪtəlɪk/ US dict: mĭks·yĕz′·pĭt·l·ĭk)"

Thank God that's cleared up for me, now I can move on with my life.
