Some people collect stamps. Others collect postcards. And then there are the collectors who take the concept of “hobby” and crank it all the way up to surreal, chaotic, and oddly impressive. From hoards of rubber ducks to museum-worthy archives of ketchup packets, these are the 17 strange collections people proudly curate, and yes, display like treasures.

1. Thousands of Rubber Ducks
