And later, you will be able to eavesdrop on a 'phone conversation between the pair. She is in Brussels preparing for one of her impassioned, no-holds-barred performances at a press conference at the European Parliament, while Paul is reporting a brief 'phone chat he had with EU commissioner Peter Mandelson - and carefully explaining to Heather how he didn't want to harass him.
Heather replies: "I'll do the harassing, you can be the nice boy."
True to form, she harasses shoppers while stalking the streets of London, beseeching them - especially those wearing fur - to take a leaflet about the trade in dog and cat fur. And if they refuse to take one, she says sarcastically: "No? Don't you care about them?"
Although her tone soon softens when she confesses: "I can't say I haven't walked past a leaflet-deliverer in my time."
She makes much more of an impact on the streets of New York, where she gatecrashes the offices of Jennifer Lopez's Sweetface fashion company --and poses for Press pictures in front of a giant image of the fur-loving superstar.
The next day's headlines - including Heather v J-Lo: A Day In The Strife - proof that Mrs Macca's tactics do pay off.
Next up is a protest outside (and, until she's chucked out, inside, where she puts leaflets in fur coats) a J. Crew store, which she urges shoppers to boycott. And at the end of the programme, it is revealed that three months after this protest, J. Crew removed fur from its American stores.
But the relentless campaigning wasn't easy. At one point, Heather says: "It's so hot, my leg is starting to come off."
Many have found it easy to mock the Maccas (I can feel my own hands starting to go up here) and sometimes, to be fair, they do make it easy for their critics.
