Three weeks later, John refused to make Sherlock tea.
Three weeks, two days later, he logged on his computer to update his blog and found the title changed to "The Personal Blog of Chunky Bear."
Three weeks, three days later, Sherlock found the name "Bumpkin Blossom" scribbled onto the tags of all his underwear.
Three weeks, four days later, the only name tag John could find to wear to the clinic read, "Chunky Bear."
Three weeks, six days later, Sherlock was forced to run to the door and scare off five different Stripper Grams requesting one "Bumpkin Blossom."
Four weeks later, Mycroft stopped Sherlock from ordering a brand which read, "Chunky Bear." To this day, he doesn't understand what it was for, but he is certain that it would have been more than a bit not good.
By the way, if you want to know what song John was playing, simply go to youtube and search "Chopsticks!" It will be the first video which shows up in the search results. It's very cool; I highly recommend you watch it.
