My fish like bread?

  Today after I got home from work I decided to make myself a chicken sandwich. When I opened up the bread and took a slice it was torn in half with the middle taken out of it. I questioned my dad about it and he said he wanted to see if the fish liked bread, so he took out the center of the slice and put the rest back into the bag. They must like it because they ate it all up! What he intends to do with the rest of the bread, I have no idea. Maybe he'll feed it to them on another day.
