Oh that Clark Kent. He sure knows how to handle the ladies.
This is from Superboy, Starring the Legion of Superheros 197. Just another example of how Clark got started with the Superdickery young. Not only does he knock poor Lana out, he leaves her lying there where any passing supervillain, and this being Smallville there's a good chance one will be along soon, can have their way with her. And all because he doesn't want to admit he's gay....err doesn't want Lana to know he's Superboy.
