He is also the most foolish, and that is also a trait associated with bards.
Thats harsh... Bards are just actor mostly. Playing a fool is actually smart!
But I'd make Bilbo a thief rogue as well, because Bard in DnD is connected with magic and as far as I remember, Bilbo was not capable of it. Yes, he had some magical/rare artefacts in his disposal, but thats it.
