What are some weird things you have found while cleaning your/someone else's room?

So back when I had step-sisters... Step-sister A had the basement all to herself and step-sister B shared a room with me.

A was in a goofy high school stage where she was collecting odd and cute things to have in her room to impress friends or whatever and one of the things she had was a Tickle-Me Cookie Monster. When you squeezed it he vibrated and said, "HA HA HA HA, HA HA HA HA, OH BOY OH BOY!"

Well one time mine and B's room was a wreck and I decided to get to cleaning it before the parental units went nuts on us. I started in the middle of the floor and worked my way outward. I got to cleaning under B's bed and I found this bulky white cased thing with a big panel on it... I didn't know what it was and she wasn't home to ask so I examined it and finally realized you could press the panel. I pressed it and was met with a loud "HA HA HA HA, HA HA HA HA, OH BOY OH BOY!" and violent vibration.

Now, young me didn't know why it was there or even why it had been removed from the actual Cookie Monster... I just knew who it belonged to so I took it down to the basement to A and told her where I found it. She bursts out laughing and runs upstairs to tell our parents. When B gets home my parents and A, with sly grins on their faces, ask her why she had taken it and hidden it under her bed... She had no response and the subject was dropped after a short reminder of "It's not ok to steal."

A month goes by and it's time to clean the room again. I'm cleaning and have the whole room done and the only thing left to do is to make the beds. I get mine done in no time and move to B's bed. When I pick up her pillow the one end of her pillow case is oddly heavy and has something in it. Before digging inside I grab the bulge it's creating and I hear/feel it, "HA HA HA HA, HA HA HA HA, OH BOY OH BOY!"

I pull it out and run into my parents room still not understanding but knowing by now that it's something scandalous and I start waving it around saying, "Look what I found in B's pillow case!" My parents start roaring with laughter and call B upstairs from watching television. She walks in and sees what's in my hand and turns beet red. That's when my Dad says it and it made sense why it was so funny, "You can't just steal peoples things to tickle your vagina with no matter how good it feels! Use your damn fingers!"
