Their skit, titled 'Oklahomo', riffs on the way the series plays with the question of Holmes' sexuality, while perfectly taking off the quick-fire deduction and verbal brilliance of Benedict Cumberbatch's Holmes, all shot with the same jerky camera movements used in the BBC's brilliant production.

The Norwegian 'Sherlock', Vidar Magnussen, who works in the entertainment department at Norway's NRK channel, claims the idea came to him as he was sitting working next to his colleague Bjarte Tjøstheim.
"I sit next to Bjarte, day after day, in the office, and eventually I discovered that he looks a bit like Watson in the series," Vidar Magnussen told Norway's VG newspaper.
The duo then went down to the channel's costume department and played around with wigs and costumes until they achieved a striking similarity to the characters.
Magnussen said he had once been involved with the BBC's Dr Who series while it was being written by Mark Gatiss, Sherlock's creator.

"There I worked with a bunch of talented people, but everyone was absolutely gay," Magnussen said. "Then I thought that there is something about that in the series. We just took it a little further in our skit."
Gatiss, who made his name in The League of Gentlemen, is in a civil partnership with the actor Ian Hallard.
