On the weapon scale, taser is a lot closer to gun than biscuit.

You don't throw them. It's the threat of having to drink your tea (yes, coffee too) without a biccy that does the damage. Withholding tea is unthinkable.

I am impressed that your weapon scale goes all the way to biscuit! I guess a stale one could serve as a projectile

England invented rock cakes (see: Harry Potter) and ginger nuts ('the original biscuits in the 1840s were "as hard as a nut"').

Although the USA can fight back with a slow HFCS poisoning :-)
