Pez Dispensers. My husband has been collecting them going on 16 years and figures by the time the grandson is his age they might be worth something. Now he wishes he would have kept the ones he had as a kid. It started by accident - one here and one there and the next thing you know he's got hundreds!
The fun is in finding unusual ones.
I think he thinks it might have been a mistake because every birthday and every Christmas he get Pez from the kids!! Sometimes there isn't even a reason. He came home from work yesterday to find the daughter had bought him a collectors edition tin of three Pez celebrating Mickey's 80th birthday. She said it was on sale and knew he didn't have it!
