"There's nothing weird about calling your baby Chewbacca if that's what you want to call your baby. It's no stranger than Sarah." So says Coldplay's Chris Martin, in defending Keith Urban and Nicole Kidman's choice of Sunday for their baby girl - and, of course, his own choice with Gywneth Paltrow of the name Apple for their daughter. Of course Chris and Ketih and Nicole (although I'm not so sure about Gwynnie) probably never got their head stuck down a toilet at school because they had a stupid name.
