All three trolls are turned to stone by the first light of the sun.
No one. Gandalf found Glamdring in a troll's cave and claimed it for himself.
Gandalf accompanied Bilbo back to his home. In addition to visiting Beorn and Rivendell, they went by the Troll's cave. They dug up the gold and silver that they had hidden.
Foe Hammer is a sword. Its name in Elvish was Glamdring; the king of Gondolin once wore it and Gandalf got it from the Troll's cave. The goblins called it Beater.
The troll face is an internet meme used for when someone tricks other person, the troll face will appear. It appears in Rage Comics on Reddit......BUT DON"T GO ON 9GAG TO READ THEM. Don't. Do. It.
Gandalf gives him a good whoopen
They are the god damn swords that the party found in the troll cave. Gandalf stabs the goblin king in the back with his.
Glamdring from the tolkien books meant star from the north if I'm remembering correctly -Glamdring is actually Sindarin Elvish for Foe-hammer. (http://en.wikipedia.org/wiki/Glamdring#Glamdring) Actually, the literal translation of glam is 'noise', not 'foe'. 'Foe-hammer' comes from glamhoth dring, 'noise-host hammer' - glamhoth is an Elvish term for Orc(s).

Bilbo trys to steal the troll's wallet. They capture him. The company is also captured. Gandalf comes and turns the trolls into stone.
They argued for so long because Gandalf the wizard was secretly saying things while in the shadows and one troll would think it was another troll insulting him, so they kept arguing until dawn.
