A few times, my dad has joked around, claiming to want some of those silly moose glasses. He does it to get a reaction out of me, because we'd all think he was nuts to want to drink out of one of those. But then again..... remembers the coffee mug shaped like Chewbacca
The only memorabilia I would truly be interested in was that adorable Victorian Advent Calendar House, the one where somebody (probably Ellen) was opening each window for each day of December. It was very cute, with a little "stained-glass" scene for each day of that month. Mom says calendars like that do not come cheap, and she's right. Obviously someone spent a whole bunch of money to give that calendar to the family. Mom says that was even a tradition that started in the Victorian Era, having a little house-shaped advent calendar, and a few people still keep it up here in the States.
Incidentally, I've done a few shopping searches for a replica of that house, and the prices are astronomical! They range from $72 to nearly $1,995! :O Damn! Even the replicas don't come cheap!
