A man in a cap and Wellington boots is holding a glistening metal pick in one hand, a small lump of flesh in the other. And he's beckoning me over.
"Hey, foreigner! Feast your eyes on this," he shouts.
Under normal circumstances, I would probably do a Carl Lewis at this point, but this is Tsukiji's famed fish market and the flesh he is rolling between his stubby fingers and admiring lovingly is from a mist-enveloped, 155-kg tailless tuna.
