Can you sponsor a worm for �4 a month?

Being very cynical about charities i was wondering about the plight of our humble earth worm.After seeing an advert asking for �4 a month to save the dolphins it got me thinking.A dolphin generally lives in the sea ,nine tenths of the earths surface,and has an i.q. of 12 .So its got plenty of room and brains,so does it really need our �4 a month or do the organisers of this charity need the �4 a month. However the earth worm only has a small area to live in in comparison,no brain, but much,much more use-full to mankind. So please please sponsor a worm today.
