Thats Not A Good Bedside Manner Dr

Regardless of different political views I would like to think that people have some basic decency and manners, but not it you are the Good Dr it seems, in his latest piece he has a pop at David Camerons comments on UKIP , I have no problem with this, but i was drawn to this piece of detail

 The video he has used for his blog post was a video done by liarpoliticians , who has done quite a few clips for this blog, but looking on the good Drs blog i could find no thanks or hat tip for the person who made the video.

Is it really that hard to say thanks or acknowledge where content comes from???
