Fish: Cabbot the Tiger Barb murdered fellow tiger barbs Master Tubby and Fundy, only after torturing them for months. Then started to shred my gorgeous angel. Peaceful my butt! Never trust a chain store. Cabbot died in a terrible "accident" the angel fish has since made a full recovery and has moved to a bigger tank.
Product: Petcetera 10 gal starter kit. I ran it for a week and had to replace the valves, the filter tubes on the UGF were too tall and I had to trim them down so they'd stay under water. The air pump grew progressivly louder until it fizzled, popped, and died a month after the tank was set up and the canopy doesn't fit the tank properly. And it has warped so the glass doesn't sit in it right, allowing moisture to get at the lights.
Fast food: More of an experiance than a product. I remember when they changed the fry names at mcdonalds. Dad had three hungry kids in the back of the minivan and he was trying to order meduim fries and the person kept insisting that they no longer had medium. He asked what they did have and the person replied "We have small, large, and super large!" My dad snapped.
We don't eat at McD's anymore. Its gross, we got much better places for fast food here.
