"Barmen" joke

Our lager,
Which art in barrels,
Hallowed be thy drink,
Thy will be drunk (I will be drunk),
At home as it is in the pub.
Give us this day our foamy head,
And forgive us our spillages,
As we will forgive those who spill against us.
And lead us not to incarceration,
But deliver us from hangovers.
For thine is the beer, the bitter and the lager.
For ever and ever.
Barmen.
