Fairly funny
The main thing I did not like about this was how long it was. If you are going to make something with that length, please put more than some screenshots for the story. I guess it's better than having the same image for the entire time. What I really liked were the accents and how out of the ordinary it was for these characters to sound so vulgar. The funniest part was easily at the beginning when they were listing the drugs.
We have so many words for them we would make the eskimos jealous. I think these are actual pictures from the books as they seem quite authentic. It's nice to know people still do parodies of classic stuff. You really didn't know what was going to pop up next with this. I thought it would be over when Sherlock said they were done with the case!
