In John 21, the disciples have been out fishing all night but haven't caught a thing.
Jesus -- though they don't recognize his altered, resurrected body -- hollers from the shore that they should toss the net over the other side of the boat.
Voila!
More fish than they can haul in -- and now the disciples know it's Jesus.
When the disciples come ashore, Jesus feeds them bread and fish he's been cooking over a fire.
