My 5 year-old just got caught feeding the fish. I said, "Is is time to feed the fish?" She said, "No." I said, "What is the quickest way to kill our fish?" She said, "Feeding them too much." I said, "OK, so cut it out." She thought for a second and said, "Actually the quickest way to kill them is to scoop them out, put them on a cutting board and Chop Chop Chop them up."
