I love the internet. Keeps me amused for hours. I came across this beer-label at Rude Food which is a pretty funny English site dedicated to rude product names (and I notice our Australian Kraft "Coon" Cheese gets a mention along with other funny stuff like FART bars from Poland).
Seems The Pittsburgh Brewing Company (the 8th largest US brewery) acquired Wanker Beer from the Kiwis nine years ago. It was established and originally marketed in Auckland, New Zealand. (The PR release said "The beer will be targeted toward young males" - no kidding).
It doesn't seem to be around anymore. A very great pity. I'm keen to get my hands on one (ha bloody ha). Seems folks just trade the labels. But I'd love to do the Advertising Campaign for this piss. Two slogans come directly to mind -
"That's My Beer - WANKER!" and "Take your hands off my beer - WANKER!"
