Rochdale - The 66 year-old humbug debunker buttonholed Clegg during a trip to Lancashire today where he was auditioning in a Herman Munster lookalike competition.
She asked him why he'd let ex-Gaddafi Foreign Minister Moussa Koussa off the hook just when he looked like cracking up.
The wily old Deputy Prime Monster appeared to 'laugh in her face' amid suggestions the British Government had just secured a massive military jet order with the Libyan resistance fighters.
Rumors that Koussa has been despatched to Qatar to secure funding for the fledgeling Libyan administration's $25bn purchase were rife this afternoon.
Duffy apparently demanded an explanation clarifying whether royal wedding bankroller the Emir of Qatar and his gargoyle wife Shaikha Mozzad were behind the latest handout.
Clegg looked gormless and uncomfortable during the encounter which saw locals declare a unanimous knock-out win to Duffy.
Miriam 'Lily Dracula-Munster' González Durántez-Clegg is 69.
