[Thor] Can Thor pick up the Excalibur?

As in the sword in the stone.

No, he likely could not.

Though we do need to have a point of order - *Excalibur is NOT the Sword in the Stone*.

The Sword in the Stone is called *Caliburn* and was enchanted so that only the true King of the Britons could draw it from the stone.  Thor is not a Briton, and certainly not of the royal bloodline.

Excalibur is the sword from the Lady in the Lake, and was returned to the Lady at Arthur's death.  Excalibur (and its sheath Avalon) were extremely powerful weapons.  Excalibur was an awesome weapon of kicking ass... and Avalon made the holder effectively immune to damage (specifically, they would not bleed).

Edit: Just to add - yes, this entirely depends on which source material you want to go with.  A lot of more modern sources call Excalibur the "Sword in the Stone"... but that still leaves the question of what the Lady in the Lake was doing.  Older sources say Arthur had 2 swords.
