Unuseless Gifts
Here is a selection of gifts for the impossible-to-please person on your list.
For those who have everything they need, here are some great things they most certainly don't.
Sky Maul
Not strictly Chindogu, since many of the items would have extreme utility– if they actually existed– but this book is the clearly the most hilarious work of crazy product-related art ever produced. From the always-useful crack pipe chess set to the coveted Llamacycle, this book has something for everyone.
It gets our very highest recommendation.
