A Man In A Pub Blows Off.....

[Chipchopper]

the froth from his beer.
The barman sees it and is not impressed and says: "Don't do that, that's a disgusting habit, look at all the mess you've made all over the bar!"

The man replies: "Well if you had poured the beer properly,in the first place I wouldn't have to do it....and just look at this beer, its cloudy!"

The barman holds the glass up to the light and says: "That's not cloudy, its just a filthy glass!"
