Heh! I caught that pronunciation, too. Caused me to wonder.
I've found that there are a few regional differences in pronunciations that are curious. For example: Where I grew up (east of Modesto, CA) farmers and everyone I knew pronounced almonds as "ammuns" (with a as in cat, u like e in the), even though all the outsiders pronounced it as spelled. I've changed to pronounce the "L", but when I visit with friends from that area, we always revert to the silent "L" version. Who knows where different pronunciations start.
By the way, the video was fun to watch.
