Yeah, they first introduced the paunchy Fifty-Something Childhood Friend of Perry White who slept with Perry's wife and was secretly the father of Perry's son and who drooled over Lois Lane and now he's the always svelte 40 year old childhood of Clark Kent who drooled over Lois Lane. All in a Superboy Punch I guess.
Though I do like that unlike in Superman:The Animated Series, comics Lois Lane was never interested in Lex at all (even before Superman arrived) and if she did go out with him it was only to get information. I like that Lois has seen through Lex from the beginning (for the most part, she's a very good judge of character).
