Narrative:

Approach control had cleared us for a visual approach to runway 25L las. Upon switching to tower, we were cleared to land and I confirmed this with the captain. At touchdown, the tower informed us that we had actually been cleared to land on runway 25R, not runway 25L. This is a classic case of miscom -- we missed the runway 25R clearance and the tower operator missed the captain's runway 25L readback.
