Steel Point Darts (Thrown at a Bristle Dartboard)
You see, what happened is that as I was at the oche I had failed to realise that my fingers were damp from excess condensation that had accumulated on the side of my freshly-poured pint glass. This led to my fingers lacking their normal purchase and the dart slipped meaning I missed the crucial barney rubble. Effectiveness - I don't understand, its not an excuse, its a statement of fact, you don't understand!
