Hobbits and presents

[Morsul the Dark]

On their birthdays hobbits give away presents as opposed to recieving them. we all know this however we do not know why.

Here's a little theory I thought up. Smeagal and Deagal were hobbits or at leasts cousings of the hobbits. Perhaps the story of how Smeagal was greedy and killed Deagal for a birthday present made them change the tradition to a far less selfish custom of giving away gifts?

any thoughts from the studio audience?
