Little arms

The question which has been puzzling palaeontologists longer than any other is what are those tiny front arms for? They don't reach the mouth of Tyrannosaurus, and the two claws at the end make them pretty useless for gripping. Compared to the dinosaur's powerful legs and jaws, the arms look feeble. They have to be there for a reason -we just don't know what... yet.
