Has anyone ever hit a homerun out of the park?

Has anyone ever hit a homerun out of the park? Only four times in history has someone hit a ball completely out of Dodger Stadium, and two of those balls were hit by Pirates great Willie Stargell. Mike Piazza and Mark McGwire also did it, but the longest of the four blasts and the first one was hit by Stargell back in 1969.
