Whoopi Goldberg described it as 'like licking a cats' bum', though was never forthcoming about how she knew....
Interesting fact about Marmite (which, I stress, is NOT vegemite, it's sort of like its 'Curry Powder' if people see what I mean?)
A great 'Lateral Thinker' suggested that we send it to the Middle East because all that unleavened bread was causing a yeast deficiency, which was leading to the sectarian violence. This is true. As one comedian pointed out, you'd just end up getting a war over those who loved it and those who hated it

Personally, I've never tried Vegemite, but I do like some Marmite on cheese and toast

I'm now hungry.
