Joan Rivers seems to be having some trouble getting work these days. "It gets hard as you get older," says the comedienne on 'Late Night' (weeknights, 12:37AM ET on NBC). "And then Betty White, that old bitch, came back ... took [the] Snickers [ad] right [beep] away from me," Rivers jokes, adding that she -- not Jamie Lee Curtis -- would have been perfect for Activia's campaign.

Making matters worse, Rivers doesn't enjoy living with her daughter Melissa for the WE reality show 'Mother Knows Best.' Apparently, this puts her in contact with "big vagina lips -- Angelina Jolie" and "those horrible children." She says Brad Pitt "doesn't know where the hell he is." And when Jolie talks about her UN work, Rivers makes an acerbic suggestion.
