David Letterman knows a little bit about stalkers.

That’s why he advised Paula Abdul to sue the "American Idol" producers — and Fox, while she’s at it —  for putting her known stalker, Paula Goodstone, on the show a few years ago for entertainment value.

Goodstone committed suicide outside Abdul’s house a few weeks ago.

Do you agree with Dave? Should she sue the heck out of Fox and AI? Would you?
