Here's how it works;
You put up three hints that will help people guess what episode of the Sitcom you're thinking of; each must relate directly to the episode in mind. The hints can be anything from quotes, story points, or even framegrabs, as long as it doesn't make the answer obvious. Once someone guesses correctly, they do the same thing you did, just with a new episode of their choice.
I'll start;
1. Someone mistakes ALF for another animal
2. Features Dogs, although they aren't very significant.
3. A character reveals his/her old nickname.
Start Guessing, and ask me any questions if you don't understand how to play!
