Not only taxonomically different as described by previous answerer, but porpoises also differ anatomically from dolphins. There are 3 main differences:
1.) Dorsal fin - Dolphins have a falcated (hooked) dorsal fin that sweeps toward the back. Porpoises have a triangular shaped dorsal fin.
2.) Teeth - Dolphins have conically shaped teeth (like an ice cream cone). Porpoises have spade shaped teeth.
3.) Rostrum (front of face) - Dolphins have an elongated rostrum and porpoises have a very blunt, small rostrum.
Also, diversity is a difference. There are only 6 known species of porpoises worldwide. There are 32 known species of dolphin.

No whoever told you that is lying or hopelessly drowned in incorrect facts. A porpise is not a dolphin but a different species entirely.

Did you really believe him that porpoises sit in front of the TV and eat potato chips all day?

No, it's not true. Dolphins (family Delphinidae) and Porposises (family Phocoenidae) are in the same suborder (Odontoceti) but not in the same family.

It is true. And whales are simply goldfish that sadly go the same way.

no they are completely unrelated. although they are both whales and can be found in similar places they are a different species altogether.
