There's a reason for that

NICK CLEGG IS TALKING TO DAVE CAMERON

NICK
Dave I've just got back from my walkabout. Have you seen the state of London? It's more of a mess then Jeremy Thorpe's brief case!

DAVE
There's a reason for that.

NICK
The streets are flooded with angry yoots enraged by the loss of their youthworkers and EMA. It's like someone cross bread NDubz with rhinocerouses.

DAVE
There's a reason for that.

NICK
The police aren't doing anything because you fired half of them and the other half are suspended for being bribed by Murdoch.

DAVE
There's a reason for that.

NICK
And everyone wants to know you stayed on holiday insulting Italian waitresses and not wearing socks.

DAVE
There's a reason for that.

NICK
You keep saying that. What the hell is the reason you shiny faced halfwit?

DAVE
The reason is...I'm pissed.

DAVID FALLS OVER.

Ha, I felt this was one rewrite away from being a great
sketch. I love Cameron's stock line (although maybe an alt. ending
could be Dave simply saying... The reason is... I just don't care. Not One bit)

Well a rewrite is neededthat's true the jokes enroute are a little lumpen.

But I prefer the idea of a punchline that says
"there's no good reason so here's a stupid one"

maybe he's the Hooded Claw or he pulls his trouser down and says "because you can see my pants"

Is "There's a reason for that" a phrase used by Cameron.
If so it's good.
If not then It's a bit weak IMO although funny
