Copies of pre production sitcoms; Sarah Silverman show

Does anyone know where to get pre production copies of sitcoms? I was checking into the writing of a half hour siitcom which is actually 22 mins. long and found out that the script should dbe way longer-something like 50 pages? At 1 minute per page, it is hard to understand.
I have chhecked on the internet and can't find any scripts for the Sarah Silverman Program. If anyone knows how to get a hold of some, et me know ok?
Any info. I can get online-preferably free like examples of preproduction scripts would be awesome. Didn't know it would be so complicated.

That's because dialogue in 3-camera sitcoms are written double-spaced and don't follow the 1 page per minute rule. There are also act and scene breaks that tend to add to the final page count.

Ohhhhhhhh.Thanks Ritchie! I have to check my screenwriting software out.
