Fish With A Whole Ox

An old man is fishing on a mountain, his fishing rod is miles long, his bait is a whole ox. He has fished for months, but no fish hooked, I mean he hasn't got a fish yet. He is still fishing. I ask him “How can you fish with a whole ox and miles long rod?!”, she says “young man, I am not fishing small fish, I am fishing huge fish?”, “How huge?”, “As huge as the blue sky!”.

I think about that for a while and now I've realized something.
