Once somebody reads one of your scripts and likes it, the first question is, "What else have they got?" And it's up to you to show them. So pick another show and do the whole thing over again. The same rules apply: it should be on for 3-5 seasons, you can't kill anyone off, etc. Do everything you did for the first script. Put just as much love and funny into it. Chances are, it'll be better than the first one.

You MUST pick another show, preferably one that's completely different from the first one. Show your range. If you wrote a Sex and the City, try a Drew Carey. Now, everyone knows you can write about women discussing sex and relationships, and about silly drunk guys.
