I still have about half of my baby teeth. I set them in pink plasticine almost 50 years ago. I also have a few teeth from my little dog - who died 20 years back, aged 17!
I kept the end of my nephew's umbilical chord, intending to give it back to him when he turned 21 but somehow it didn't seem appropriate when the time came.
Oh, and when my large lop-eared rabbit died, I had him stuffed!
Not all New Zealanders are weird but some are!
