The Anna Nicole Smith DNA paternity case has been pretty clear-cut so far – Howard K Stern is the evil one, Prince Frederic von Anhalt is the mental one and Larry Birkhead is the nice one – but now Larry’s status might switch from ‘nice’ to ‘creepy’.

Although Larry Birkhead has long been the popular favourite to be named as the father of Anna Nicole Smith’s baby – partly because he seems to make a good case for it and partly because he’s not Howard K Stern – he’s decided that the potential hundreds of millions of dollars that he’d get as Dannielynn Hope’s father isn’t enough, and has trademarked the creepy phrase ‘Goodnight, My Sweet Anna Baby’ for use in movies, books, TV shows, internet shows and stageplays as well. Luckily, though, Larry Birkhead hasn’t trademarked ‘Goodnight, My Sweet Anna Baby’ for use on novelty stationary – so we’re taking that for ourselves. We’re guessing that kids will love our range of horrific clown-faced Anna Nicole Smith pencil cases that menacingly intone the phrase “Goodnight, my sweet Anna baby” each time they’re unzipped.

Hey, if everyone else is making a buck off Anna Nicole Smith, we may as well join in too…
