I'm a Pain but I Don't Care

So you know how everyone says being the youngest means you get away with more stuff? Well yeah, totally true. And here's what happened last week at home: Mom was out buying groceries and I was watching my siblings' favorite show on TV when Big Sis came in all mad because she couldn't find her phone charger. She started yelling that it must be mine, like seriously, why does everyone think everything is mine? So I told her to calm down and that if it's anywhere in the house, she'll probably see it soon enough. Then Dad got home from work and was grumpy about something, so he asked me to turn off the TV because the kids need quiet time before dinner. But you know what, the show was only five minutes away from ending! So I kept watching until it did, and then turned off the TV with a big smile on my face. Dad just gave me that look like 'You are driving me crazy,' but honestly? It's worth it to annoy them sometimes. Now here's what I need advice for: How do you handle when they all gang up against you? Like today, Big Bro and Big Sis teamed up to remind me I still owe them from a prank I pulled last month, which is fair enough. But isn't it my right as the baby of the family to take a little longer with payback or whatever? What do you guys think? Is this how youngest siblings should act?
