They have inferiority complexes.
In other news, I just discovered that my cable service/ISP has free eps of Firefly online. I just spent the last 45 minutes watching "War Stories" - it was the best time I ever had folding laundry. BTW, while I think Whedon's work swings wildly between highs and lows, Firefly seems to me to be the almost perfect combination of writing, backstory, and casting in a TV series. Even the mediocre production values can't take anything away from it. I could spend three hours just writing about the ep I just watched.
"We've been over this. We don't shoot first and ask questions later."
"Of course! We never ask questions."
