I'll admit you can figure out a lot from deduction, but the insanely accurate conclusions Benedict Cumberbatch's Sherlock Holmes manages? That's stretching the old suspension-of-disbelief a tad.
So what if Holmes was just really terrible at pumping out swathes of exposition from a splotch of mustard or scratches on a mobile phone? You know, like the rest of us?
The fortunately-named Pete Holmes had a go at presenting this particular reality a few days ago in the above clip. Shot in the same style as the popular UK show (itself based loosely on the protagonist of Sir Arthur Conan Doyle's novels), it does make you think Holmes could play it safer by being more generic with his deductions.
Hey if it works for psychics, it can work for detectives!
