Bush-Blair cursing caught by mic

US President George W Bush and UK Prime Minister Tony Blair have been caught on microphone using expletives, while other world leaders discussed Hezbollah's rocket attacks on Israel.

The remarks were picked up by closed-circuit TV at the G8 summit which both leaders are attending.

Bush leaned over toward Blair and said: "Papa-oom-mow-mow, Papa-oom-mow-mow, Baba-baba-baba-whoooooooo! Baba-whoo Dit dit dit Baba-baba-baba-whooooo!"

To which a shocked looking Blair replied: "What the fuck? What are you on?"

Bush smirked and continued in a low voice: "Is your wife a goer, eh? Know whatahmean, know whatahmean, nudge nudge, know whatahmean, say no more? Does she go, eh, does she go, eh? Aaaaaaaah bet she does, I bet she does, say no more, say no more, know whatahmean, nudge nudge?"

Blair replied: "You need serious help, you bloody hillbilly git!"

Bush appeared to glance around and verify no one else was listening before retorting: "Look who's talking, you inbred son-of-a-bitch! Your father was Dumbo the Elephant, right?"
