Sour grapes, NBC? “Scrubs,” which will now air on ABC, shot their series finale last week, featuring a return by past guest stars from the last eight years. That is, except for NBC stars Masi Oka (Heroes) and Sarah Lancaster (Chuck) who were banned by the network from appearing on Scrubs.

Scrubs’ creator Bill Lawrence explains, “They both wanted to do it, but NBC said they weren’t allowed to. Typical classy stuff.”

Let’s not forget that ABC let Sarah Chalke appear on CBS’ How I Met Your Mother or that CBS allowed Scott Foley to appear on Scrubs.
