Head can, head can, head can, head can

There's a practice that I've heard of but I'm not gonna follow
I've seen it spread around in all sorts of old films now
Pretty simple to describe it when you're dared to try it
All that is missing is the "Why?"

What's with the head can nonsense? Why's that so common now?
Stupid head can to prove you're strong, not right
Don't like the head can bollocks, my standards aren't that high
But I'd rather not do that crap on any night
Stupid head can, head can
Stupid head can to show you're strong, not right

You can say that I just know that I'll fail like that's the one problem
That anyone could have with just 'bout anything now
Because open cans that are sharp? Pressed against your brain shell real hard?
Only weirdos would think twice

About the head can nonsense that's so damn common now
Do the head can to prove you're strong, it's fine (pretty sure it's fine)
Keep up the head can bollocks, the scars should fade in time
A pain in the hole for recycling centre types?
Screw 'em, head can, head can
Do the head can to prove you're strong, so fine (yeah-eah)

Gotta say, all that was fun
Sarcastic lines, never lose their punch
Good bet that my song's target won't
Understand that I have done so, have done so, have done so
Because the chances are quite high, beer's the head can
Head can (I'm pretty sure I'm right)

Don't like the head can nonsense which is real common now
Stupid head can to prove you're strong, not right (sorry, it ain't right)
Those who love head can (head can) bollocks (bollocks), this "stop" of mine's polite
'Cause you'd likely fold me in half so please think twice
