This was a while ago now but... I was roleplaying at university and got a christmas card from my GM. In the game I was known for being pretty unlucky, and any re-rolls I had never worked. The card included a little message about that.
So I went back to my parent's home for christmas, and left the card there when I came back to uni for the next term.
Now my mum is very anti-drugs, but I never partake, so I was a bit confused when my dad rang me up saying how upset my mum was over my drug taking. I asked what he was talking about and he told me they'd read the christmas card that said...
"May you always pass your re-rolls."
Yeah, so they'd taken that rather the wrong way, but I found it pretty funny.
