What is the Heather mills/tarzan joke?

[crofty1984]

Odd post I know. I was listening to theat mitchell and webb sound this morning, and the last sketch was a send up of various famous jokes and comedy moments (Shirley got a mention!), but I didn't recognise a heather mills/tarzan reference.

For those interested:

Hello, I'd like to buy four candles please
There you go
Thanks, also, can I have some fork handles?
Anything else?
Yes actually, I'm sorry to say this, but this parrot I bought yesterday..
Oh my goodness, it's dead!
Yes, it is.
I'm ever so sorry, have this new parrot, and here's £50 to compensate you for your trouble.
Shirley you cant be serious?
Oh, how nice of you to remember my wife's name (Hello!)

etc, etc.
