I should of killed my brother omfg

So me and my brother are always joking. So one day my mom made up put the groceries up in the fridge. So she bought all these things and my brother just happened to pick up a cucumber. So me being me i joke about it and say thats not for eating. And i start dieing because of his reaction he throws it out his hand being all extra lol. So he runs upstairs and totally snitched on me. He told my mom and her boyfriend. I couldn't help but laugh but nobody else thought it was funny but me lol. Idk after that nobody has ever looked at me the same but im still laughing about that. I think i should of beat his ass for telling. So my mom gave me a speech and everything like its not that serious. And here's the messed up part he's 18 telling on me lol. Like get a life kid.
