Only the British would put BEER in a one gallon can. I love it!
The comedy sketches are unlimited. "But officer, I had ONLY one can of BEER!", "It's how much for a 6-pack?", etc., etc.
A six pack of those babies would strain enough muscles, you would need the whole six pack for relief.
A UK gallon is 1.2 US gallons. Depending on the BEER, a lightweight lager or a Wee Heavy from Scotland, a gallon could go 8.5 to 9.5 lbs (US) per can.
I need to borrow your hand truck, I'm picking up a 6-pack.
