Marmite: Love It! (but actually hate it)

Marmite has really embraced their love it or hate it status and turned it into a clever campaign. More recently, they've launched a cereal bar.  The ad again plays on those who love it's obsession with the product. How great is this?

Maybe I should give Marmite another chance... 

PS How did they get that Unilever logo in the top left? I don't think Unilever owns them?
