I don't drink alcohol, so why I was attracted to Baileys Yum cups [which advertises Baileys Irish whiskey and cream liqueur] is beyond me! But several years ago when I saw the boy and girl cups, I thought they were fun and cute, and bought the pair.
Recently while browsing in an antique store I came across the matching sugar and creamer. The set was inexpensively priced [as were the cups I acquired], but I passed on getting it. Later on, it occurred to me if there were cups and a sugar and creamer then there must be a teapot. I went online and discovered there is. A teapot went in an E-bay auction Monday night for $53 plus shipping. He's cute, but my wallet didn't think that cute! ;-) There are also cookie jars.
The Yum products were made in limited editions in the 1990's so they're collectible, but not antique.
I returned to the antique store a few days later and the sugar and creamer were still there so I bought them.
Have you ever purchased something just for the fun of it?
