From some real conversations:
Where do you get them from?
I trap them in my back yard.
What are those plants?
Rare imports from one of Jupiter's moons.
Is that saltwater?
Nope, it's synthetic seawater.
So it's not real water?
No, it's mostly baby oil.
I still think the clownfish needs a house like Nemo.
Well, he wants one, but he can't afford the down-payment, and the points are killer.
So you still have the fish?
No, I traded in tens of thousands of dollars worth of livestock and equipment in for something far more practical, a submarine.
So you really still have the fish?
No, they all died, what you see floating in the tank in front of you are all fishy-ghosts.
That's too much work.
Really? And spending 16 hours per week on some live rug in front of your house isn't?
You paid how much for rocks?
Well, let's just say I don't purchase those wrestling pay-per-views monthly.
Are they alive?
No, they're robotic.
How much would it cost to set up something like this?
You could probably afford it, but I don't think you could do it.
What the heck is that supposed to mean?
It means that, if you knew how to do it successfully, to keep it going, you wouldn't have to ask that question.
So, did you get any new fish?
Nope, just the same old ones. Next week, I think I have to get one of those a wheelchair.
How come they don't die?
Because I do my best to know how to care for them.
See, I told you they would die.
One fish? After 12 years? How old is your dog?
There are tons more, those are just a few off the top of my head.
