"You either love me or hate me, like Marmite."
Quite simply this is a rubbish thing to say. There's nothing to gain by hoisting this garbage out of the doldrum zone of your mind and transmitting it by any known method of intelligible communication. You missed clever (it's only clever if you came up with it after that it's copying), missed funny (can you say "diminishing returns"?).
You know what? It's not even true anyway. In reality alot of people think Marmite is the manifestation of meh - they can take it or leave it. And hell, I challenge you to find someone that loves Marmite. On your marks, get set, go. You lose. I'll find someone who loves Walkers Sweet Thai Chilli crisps before you can find someone who loves Marmite every time - it just doesn't have much in the way of luvability.
Hi-fives for the guys and gals at Marmite for unleashing an ad-campaign that mutated into a brain eating monster. You earned your pay - way to lead by example. As for anyone else, read the signs: no riding the brain eating monster. No matter how stupid you are, having your brain eaten isn't good for you.
