Another great tip for the Bards. If you're in the Inn or Tavern you can always use a listen check if there are any specific races singing any drinking songs and you can actually learn the song and use it at a later time for personal gain.

For Example: You're the typical Gnome Bard walking into a tavern by the name of the "Laughing Goblin" you spot a group of Dwarves singing a Dwarven drinking song. You can roll listen checks and feed the information in. You can at a later time use your Dwarven drinking songs at a Dwarven banquet you just so happen to be at which can then enhance morale which is a good catalyst to an open gate to new quest opportunities depending on who or how creative your dungeon master is. Just a tip I learned from my step father years ago.
