Short sketch I've written. Hope you like

Presenter
As the UN discusses the use of killer robots we ask: Killer robots, are they bad news? I'm here to today at the death by robot institute of intelligent design to talk to a killer robot. Good evening killer robot 2-6-9-9-1-8-8 epsilon 9-2

Killer Robot
Please, just call me graham.

Presenter
Well graham, do killer robots get a bad rap

Graham (Killer Robot)
I find your query very interesting KILL, pardon. People find it difficult to look past the mass murder and genocide but we're all really quite friendly. I myself quite like cats

Presenter
Have you ever killed people?

Graham
Oh yes, hundreds.

Presenter
And what do you do when you're not killing?

Graham
I like to relax with a glass of WD40 and think about killing

Presenter
In your opinion, are killer robots dangerous?

Graham
I've never unintentionally hurt anybody

Presenter
How do you decide who to kill then?

Graham
I'm controlled by a smart phone app, so I can only ever do as the app tells me. It's very safe. I've only been hacked into twice.

Presenter
What would happen if you ended up with control of the app?

Graham
hmmmmm.... ... ...

Many screams of pain and death

Graham
Oh wow, there's angry birds on this

It's not bad it just needs to to be tighter.
The dialogue is on the money, but the punch is weaker than it should be.
You also need to describe the robots action rather than 'Many Screams of pain and death'
If he had the man over his head and was about to throw him out the window and then discovered angry birds making it a close call it might scan better.
The idea is fine and the dialogue is good so its worth tinkering with.

cheers for the feedback. should have mentioned it was done with radio in mind
