A young, female Teacher is having a show-and-tell in class today, and all the kids come up and talk about their pets. They go up and talk about their dogs, goldfish, cats, and so forth. Nothing out of the ordinary.
Then Vlad comes up and says:
"We have a family pet. He's an Owl On Wheels."
The Teacher responds:
"An Owl On Wheels? Tell me more - why isn't it here with you?"
"Oh, he's a very special family pet. He never leaves the house; if you want to know more about him, I would suggest that you visit us sometime."
The Teacher, intrigued, comes over to Vlad's house the next day. She rings the doorbell, and the father answers the door.
"Hello, I'm here to see this Owl On Wheels. It sounds very interesting."
The Father says:
"Oh, well, you can't just see right away. It's a very important, special pet of the family. You have to approach it in a certain way. Go down the hallway into the living room and stand in the center."
The Teacher is bemused, but this only fuel her interest further. She does so and and stands still in the middle of the living room, where Vlad and his Mother is.
"Okay, now can I see this Owl On Wheels?"
The Mother says:
"Be patient, there is one more step you have to take before you get to see the Owl on Wheels. Strip down naked, to the bone."
The Teacher is mildly taken aback by this, but she's gone too far to back out now, and she's determined to see this Owl On Wheels. She strips naked, standing in the middle of the room. She's quite impatient now.
"Okay. Can I see this great Owl On Wheels now?"
Vlad opens the door and calls:
"Grandpa!"

"HOO HOO, HOO HOO, HOO HOO!"
