In our family, every year we would give the same presents.
My Dad would wrap up a potato in lots of newspaper and put it under the tree, one for me and one for my brother. He then did this for my daughters as well.
We always had one fun gift, One daughter always got a coffee mug, she has quite a collection now. The other always got funny underpants. I would search all year for both. My husband still gets a cigar (his one a year) and I get good chocolates.
What do you do that is unique to your family?
