Television
"How can you waste your time sitting around watching that," Sherlock asked from his place lying on the couch, sounding genuinely perplexed. John shrugged.
"It's good to unwind, I suppose." Sherlock scoffed.
"Unwind? You can relax by sitting and watching that idiocy?"
"Not all of it is idiocy. Sure, a lot of programmes out there that are pointless and insipid- but there are still some useful and entertaining things on." Sherlock looked pointedly at the episode of Doctor Who playing on the nearby screen, David Tennant shouting about taking down a giant robot that was destroying Victorian London.
"Name one useful thing that you've ever gotten out of that box." John tore his eyes away from the screen and finally glanced over at Sherlock.
"I learned how to affect a convincing American accent, for one. If you listen to one long enough it's not hard to pick up." Sherlock frowned. That had been rather useful to John's fake back story in the case they had worked last week. "Second, when I was four, it was how I learned the Earth went around the sun."
"I would hardly call that necessary-"
"Even after the ordeal with Moriarty? There are a lot of important cultural, scientific, and common sense things you can learn by watching the telly." John looked at the time on the cable box under the television, sighed, and stood up. He was late getting ready for work.
SH-SH-SH
John came back down the stairs from his room and could only blink in surprise. Sherlock, instead of just turning off the TV like he had expected him to, was actually watching something.
"What are you doing?"
"Scientific research. I'll admit, you could have, possibly, made a good point." John walked closer to the television and tried to recognize the show. Wasn't that the one Molly had rambled on about once?
"And what sort of research are you going to get out of this, again?"
"I can get information on a wide range of obscure superstitious beliefs and an idea of the differences between regional American accents." A man on screen was frantically pouring lines of salt in front of doorways and windows.
"You do know Supernatural is filmed in Canada."
Sherlock ignored him and turned up the volume.
