This is a parody of the Lord's prayer about typical London Chavs. The reference to rioting and looting concerns the London Riots. Those from outside the U.K. may not find this as funny as those who are.
The Chav Prayer
Our father
Who art in prison
Mum knows not his name
Thy riots come
Read it in The Sun
In Birmingham as it is London
Give us this day, our wellfare bread
And forgive us our looting
As we're happy to loot those
Who provide for us
Lead us not into employment
But free council housing
For thine is the Flatscreen, the Burberry and the Blackberry
Forever and ever...Innit
