I think Chris just needs more focus to what he's doing. Both the Microsoft Attack and the Perfume ad could have been full length episodes, but they seemed rushed together.
The reason the Jack Thompson (and the Voice Man) episode worked so well was they had solid form, well timed jokes and a good punchline.
I'd humbly suggest a little more brainstorming before you jump behind the camera, get everything out of the joke that you can.
For instance, in the Perfume Ad, where he thrusts his arm at the audience, you can see his armpit, so... exaggerate it by having a huge ball of hair there.
