<<<Your analogy of a baby's fist is quite unsettling.>>>
???? Going into seppock mode here, I'm afraid. I am completely lost for a response, honestly. I have a feeling some of us are about to learn something very very deep and basic about the British mind, or else uncover a major brainfart on my part (very possible. I am edging into Senior Moment territory. Be honest about it). I mean, babies do make fists, especially when they're upset or perhaps blowing off. And there, a cute little object of ready reference size. Please elaborate.
As for the haggis thing. The USDA and FDA are noted for being exceedingly conservative about allowing the US populace to come into contact with anything that proves in the faintest degree toxic (oh, except alcohol, tobacco, and fireams. Those items are covered by the ATF (Bureau of Alcohol, Tobacco, and Firearms--honest, they're all lumped together! Hey, they're mainly concerned with tax revenue derived from the sales thereof. Hmm.....). Considering the dangers of drowning and burning to death, I'm surprised we're allowed to drink water and breathe (air contains oxygen, do note). So, even though the scrapie prion in sheep innards is apparently not transmissible to humans, it is, well...what? Bureaucrats (*sigh*!) I'm never surprised when the USDA and FDA seek to protect us from anything more toxic than sand or sharper than a rubber ball.
