How,
Twix is a god
A plain boring biscuit, with caramel, and a thin layer of milk chocolate.
It's just so boring. The biscuit isn't anything special, the caramel is just to give it a flavour, and the thin layer of chocolate is just to make you think you're eating something nice.
There are better chocolates, and there are better biscuits.
Twix is a mediocre middle-ground.
