If all that's preventing Clark Kent from being recognized as Superman is his glasses...
...then what about all his government issued photo I.D.?

And speaking of [i]that[/i], since Cyclops can never remove his glasses, does he even [i]have[/i] any photo I.D.?
I'm thinking he either better make sure he never gets pulled over when he's driving as a civilian, or he's been given a pass on the "no glasses" photo rule by instead having "MUTANT" stamped across any card he has.
