Why would you put yourself forward for a TV quiz show when your general knowledge is APPALLING?
When you confidently proclaim that you know about geography/rivers then think that the Thames runs through Cambridge? Or when you think that out of "feline/cat" and "alpine/alpaca", that Alpaca is correct? Or that alkaline refers to frogs, and guillotine to gulls?
Fuck me. The producers are clearly testing people, discarding those of average intelligence or above in order to keep the budget down.
