Sherlock Holmes's emotions run very high when he solves a case, and he is liable to do anything.
UPDATE: Hello everyone looking up SH stuff since the movie came out! Thank you for making this vid very popular! Now, Peter Serafinowicz has been very nice about not making me take this down, so it would be nice if you returned the favor by visiting his website (http://www.peterserafinowicz.com/) or following him on Twitter (@serafinowicz). Also, you can buy the first series of the Peter Serafinowicz Show--where you can see this clip!--from Amazon.co.uk
Also, I do my best to remove spam comments at least once a day, so I thank you for your patience, and I'm sorry if I accidentally remove your legit comment by accident.
