Last night on the Daily Show, host Jon Stewart skewered Fox News’s Bill O’Reilly for claiming Bristol Palin’s pregnancy is “a personal matter,” when last year he pointed the finger of blame at Jamie-Lynn Spears’ parents — “who obviously have little control over her” — and called Spears an “incredible pinhead” when she revealed she was expecting. Stewart joked, “You see what happens with opinions over teen pregnancy is that they gestate over a period of months.”
