Put it near the end of a dare or food-challenge edit, right after the worst option is shown. Lead in with No No Wait Wait, let this line deliver the refusal, then close with Eww Brother Eww for the group's reply.
O tym dźwięku

The crude eel comparison is deliberately shocking, and that awkward absurdity is what makes listeners laugh instead of taking it seriously. It was taken from material by Kesyn & Skelter.
