Frightening gift for the kids?

Great thread, 4flats! Got two stories for you.
The first is one I remember from when I was about 10. My mom was the ultimate Christmas snoop and thought everyone else was as well. So, this particular Christmas she decided she would wrap all the presents and not put any name tags on them since she was sure she could remember each gift and who it was for.
All went well until my grandfather, who had a vocabulary as colorful as a cross between a Marine drill instructor and a Merchant Marine sailor, opened his gift, held it up and loudly asked, "What the *$@&^!%$ am I supposed to do with this?"
He'd opened up a gift obviously intended for my sister, a new bra.

The second is the Christmas we got my 4-year old daughter a new swing set for the backyard. The original plan had been to put it together and set it up in the backyard after she went to bed on Christmas Eve. Well, that year it decided to rain for a solid week before Christmas and continued on into Christmas day.
We ended up giftwrapping the huge box and putting the long cardboard box on the living room floor in front of the Christmas tree with bows all over it.
Even at 4 years old she didn't buy it - saying there's no way Santa could get that box down the chimney and how come it's wrapped in the same paper as the other gifts that didn't come from Santa.
