While Sherlock and Mycroft both know multiple language, John enjoys cussing them both out into Pashto (language spoken in Afghanistan) and giggles like a maniac because neither of them understand a word he was saying. He thinks it's great fun. He also enjoys sing army slang. And occasionally Australian or American term to confuse them even more.
