...Friday the Thirteenth.
Here, it is considered a day of bad AND good luck... So, there is usually an extra lottery drawing on those days when we have a "von' druh dee trehz."
Note where it says touchez du bois. That means "touch wood," which is what they say here instead of "knock on wood." It's supposed to bring good luck...
I've found over 300 four-leaf clovers in my life and haven't won the lottery, so go figure whether that one works or not.... LOL!
