Non veni pacem mittere, sed gladium.
That's why you have your pocket knife, to gently slit the top pre-straw insertion. However, in England, pocket knives are illegal. Fortunately tomahawks are not, but it's more complicated to use a hawk to gently open the top of the beverage container.
But in England the police are also unarmed, so if they harass me there I'll whip out my three inch blade and back those limeys up.
You need a bigger blade than 3" if you intend to keep your reputation in the Faroe Islands intact.
If a Faroese lassie asks to see my blade, I'll oblige.
Why?: Blonde female, of course.
Geez, this is why blondes get such bad press...
