This isn't really a prank but one time I made a smoothie without my mum's permission so I made my sister say she threw up when I couldn't pour it down the sink

So friend C and D went with my older brother to go bring back some food and I waited at home with my other two friends. Then friend A says, "Usually this is the moment we plan to pull a prank like in those cliche movies." and we thought for 3 seconds before friend B goes away and walks back with friend C's socks that she left behind and we decide to hide it... in the freezer.
We took a plastic bag and put her socks in it (for hygiene reasons ;P) and friend A says, "We should put a bit of water in it so that her socks are a little frozen." and I ask, "What about friend D?" and so friend B disappears again and comes back with friend D's glasses case... and we decided to instead stuff the socks into the case and place the case in the freezer.
When they came back with food, friend C heads to the room she left her socks in and comes back looking confused, "Guys, where's my socks?" and we kinda shrugged (and she rolls her eyes sassily saying, "You guys had one job.") before friend D goes to help friend C to look for her socks and we silently laugh before they come back, friend D saying, "Hey, I can't find my case. Where did they go?"
Friend A literally has a troll face when saying, "We hid it..."
"Where?"
And friend B joins in, "We'll play a game of hot and cold."
Obviously, that continued for a while before friend D looks in the freezer and takes a moment to realize that her case is in there and when she takes it out and open it... well friend C looked traumatized for her socks and friend D starts yelling at friend A because that was just friend A's personality so it was easy to guess who planned it.
My older brother looks kinda confused asking, "What happened?" and I explain everything to him and after the scolding friend A walks over and doesn't look apologetic at all, "I'm disappointed that we didn't put water on friend C's socks." and walks away [and my brother didn't hear so I repeated for him] before my brother replies with, "I'm kinda disappointed too."
