General Randomness

They're coming thick and fast this week.

Mr B asked me last night what Marmite was made of... yeast extract says I.

"Yes, but WHAT exactly is yeast extract, and how does it get made?" he says.

"Dunno" says I, "but how in the heck was it discovered.....????

long pause...........

.....What would have happened if the first person to discover Marmite didn't like it?"
