(Armstrong and Miller RAF pilots 'D-Day' - please note that the characters are very politically incorrect while claiming to be well-versed in "diversity" issues)

I think the writer sets the comical scene very well. In the first bit of the scene the sergeant says "All right chaps, are you ready", in a casual way which makes it seem quite funny, because realistically a sergeant would be shouting like mad telling his men to get ready. Also, it could be seen to be quite funny because the sergeant says "get ready for war", in a jolly way which could be seen as humour.
The two men Armstrong and miller also make the clip quite funny because they are dressed like they are ready to go on holiday but yet they about to enter a war-zone, this can be seen as funny as the writer has made it ironic. It's also quite funny and ironic when the sergeant says, "right men, you know what to expect on that beach", when he says this you see Armstrong and miller with a beach toy and a bucket and spade - this makes the scene ironic and funny, as they are about to enter a battle.

The clip is quite comical as the two men use a quite controversial register, as they chat to each other in quite an informal/colloquial way, which gives the impression that they are friends, as they talk about quite graphic things, like "ladies costumes, pubes" . The two men make the clip comical more so as their sociolect is an upper class tone, which is ironic as most of the upper class people during WW2 would not have to had of fought. Furthermore the two men come across ignorant when they say that they're not racist, but yet they use rascist terms - this makes it ironic which can across as humour.  The way the conversation between armstrong and miller opens up, it starts to go into a phonological rhythm which makes the play not just more comical but it  makes it more enjoyable.
