John found Sherlock at the kitchen table, perched over a contraption of several magnifying glasses on top of one another. His hands were both holding some sort of tool over a... was that a hearing aid?
"Sherlock what are you doing?"
"Working"
"Thats not work"
"Ok, not working then."
"Whose hearing aid is that?"
Sherlock looked up. "Do you remember that eldery man who was in here yesterday?". "Yes". "Its his". Right ok. "So you're taking it about why?".
"Because it was bugged."
"Bugged?"
"Yes. He left it here on purpose."
John sighed, rubbing his temple. "And you know this how?". "Because I called him and he said he didn't lose any hearing aids.". Sherlock gave an exclamation and held up some little metallic thing.
"Is that the bug?" "Yes!" He smashed it under his foot.
"Why didn't you just do that in the first place?"
"More fun this way"
"Ok, who bugged it then and why?"
Oh John, surely that was obvious. "Who else but Mycroft? He's been trying to get his ears in here for months." "How do you know?". "You remember the toaster?" How could John forget?"
"Of course, you threw it out the window, with my toast still in it!"
"It was bugged too"
"Who bugs a toaster?"
"Mycroft"
John gave up. This situation was ridiculous. "Whats next then, a hair dryer? Is he going to bug microwave next? You Holmes's I swear you're just completely ridiculous."
"Why would he bug a hair dryer, do try and make some sense John"
John just laughed.
