Y'all realize the network lines are rather blurred now right?
Examples;
How I Met Your Mother- Fox show that airs on CBS (with Sarah Chalke who was simultaneously appearing on Scrubs on ABC, as well as guest stars from NBC)
House- NBC show that airs on FOX
My Name is Earl- Fox show that airs on NBC
I doubt network affiliation will be an issue.
"Grease," the fourth revival of the season, is the worst show in the history of theater and represents an unparalleled assault on Western civilization and its values. - Michael Reidel
