AJ: Mom, I got a fish from the creek.
Mom: Put it back it'll die.
AJ: I've had it in a bowl for 3 days; it won't die.
Mom: Well it's gonna die; put the poor thing back
10 months later
AJ: Mom, I gotta 'nother fish.
Mom: From where?
AJ: From Mikey; he got 10 for a dollar.
Mom: Well don't put it in the same bowl as the other fish; they'll fight
AJ: I put them both in the big aquarium (the 10 gallon one in the laundry room that once held ever multiplying gerbils)
Mom: Why'd you put them in there? You have to have a filter in that big aquarium. You can't keep dumping the water out and re-filling it. They'll be dead in 2 days2 days later
Issac the creek fish and Marvin the goldfish are happily swimming around in a 10 gallon aquarium, that we'd better go get a filter for.
