I think this sketch would suit the radio best.
UN SKETCH
A DISABLED MAN, A HOMOSEXUAL AND A GYPSY HAVE ARRANGED A MEETING WITH THE HEAD OF THE UN. THEY ENTER HIS OFFICE.
HEAD OF UN:
What can I do for you gentlemen?
GYPSY:
Well it's a bit awkward really. You see the three of us feel a little hard done by.
HEAD OF UN:
(LOOKS THEM UP AND DOWN) Well I can see that but what does that have to do with me?
HOMOSEXUAL:
(WHISPERING INTO GYPSY'S EAR). Tell them about the Jews.
GYPSY:
Do you know the Jews?
HEAD OF UN:
Of course I know the Jews. Throughout history they tend to pop up from time to time.
GYPSY:
Well do you know World War 2?
HEAD OF UN:
(SARCASTIC) The war that resulted in the creation of the organisation that I am the head of. Yes, I think it rings a bell.
GYPSY:
Well after WW2, because the Jews were badly prosecuted by the Nazis, the allies gave them there own country. But other minorities were persecuted too and they stand before you today.
HEAD OF UN:
I don't like were this is going.
THE HOMOSEXUAL PUSHES THE GYPSY TO ONE SIDE.
HOMOSEXUAL:
Listen to me girlfriend. We are not leaving until we have got our own countries for our own peoples. (STAMPS FOOT)
HEAD OF UN:
You in the wheelchair, is this what you want too?
DISABLED MAN TYPES INTO HIS SPEECH MACHINE
DISABLED:
No-i-just-want-ed-to-be-left-at-home-so-i-could-die.
GYPSY:
(SHOUTING AT DISABLED MAN). Listen, we have to stick together if we want justice. And don't forget that Hilter used to push your people around.
DISABLED:
I-wish-some-one-would-push-me-a-round.
HEAD OF UN:
OK.OK. I suppose we can find a few scraps of land for you guys and we can always do with some more allies.
HOMOSEXUAL:
I'll need somewhere hot, hot, hot!
DISABLED:
And-I-will-need-some-whore (PAUSE) sor-ry-my-fin-ger-slipped-some-where-flat.
HEAD OF UN:
I've got just the place. We can split up a part of Mexico for you guys. For some reason whole areas are now unpopulated. I will have Thatcher whacked and announce the new countries the same day. That way no one will care about the new countries for long.
HOMOSEXUAL:
I didn't want anyone to get hurt.
HEAD OF THE UN:
She should have thought about that before she stopped putting out. All I need now is the names of the countries.
HOMOSEXUAL:
My country shall be called Homotopia.
GYPSY:
I think Ill call mine Gypsystan, after my late uncle Stan.
DISABLED:
I-want-my-coun-try-to-be-called-euth-an-as-ia-fant-as-ia
HEAD OF UN:
Seriously?
DISABLED:
No-I-was-be-ing-sar-cast-ic-how-did-you-not-get-that?
Very funny - but I agree with timbo & Sootyj re. the length. I've trimmed a bit and added the necessary exposition for radio - oh and a couple more gags - plus a punchline I couldn't resist!
