I always used to make jokes to my mother, because every Dec 25th she'd invite the entire family round and we'd have a huge turkey dinner, give presents and drink all day. It wasnt Christmas, no, no... it was simply because there was lots of turkey in the shops and we might as well eat it. And everybody's off work so we may as well get together. And there's lots of great toys and gifts in the shops at the moment so we may as well do our "suprise day" today seeing as we're all together.
But it wasn't Christmas. No, no. It's "a family get-together".
I used to wind her up by clinking glasses with the person next to me and saying "mazel tov!" - it wasnt "cheers" or "drinking to the gods" it was me saying "congratulations in Hebrew".
