I bought a big aquarium at hobby shop in town
My buddy had a pick up, so he helped me haul it down
It held two hundred gallons, it was not a tiny tank
We got it on a hot day, all those gallons coulda' drank
(Piranha, Piranha, Piranha, they threw one in for free)

I didn't know too much about the fishy business
What not to put together, so I had to make a guess
I bought some snails and puffers, and guppies that would gup
An awful lotta; goldfish, 'cause I heard gold goes up
(Piranha, Piranha, Piranha, they threw one in for free)

I bought a dozen devilfish, six angels for suspense
Also a couple swordfish, will be fun to watch 'em fence
Then, I got a little sharky, 'cause I liked that movie, "Jaws"
I am real sure of one thing, won't feed him with my paws
(Piranha, Piranha, Piranha, they threw one in for free)

Instrumental interlude--------

(Piranha, Piranha, Piranha, they threw one in for free)

I hooked the garden hose up and the water poured in slow
Tossed in some rocks and green stuff, placed a shipwrecked hull below
Plugged in the pump, turned on the lights, stood back and gazed with pride
Now, comes dramatic moment, I dump the fish inside
(Piranha, Piranha, Piranha, they gave me one for free)

My friend and I were loaded from the case of beer we drank
So, he went home, I jumped in bed..my wife said, "Stop, you Skank!"
Next morning I remembered, that I forgot fish food
I ran to the aquarium, but gone was all my brood
(Except)
(Piranha, Piranha, Piranha, they gave me one for free)
(Piranha, Piranha, Piranha...ate all other fish-ee)
