I suspect that the following are a bit more the sorts of replies you had had in mind:
Perry discovers that bungee jumping is fun.
Clark Junior discovers that Clark Senior is Santa Claus.
Lois discovers that she is pregnant. (Or Clark discovers that Lois is pregnant. If he realizes it first, it might make for a more interesting story. And given his heightened senses, he would probably hear a second heartbeat coming from Lois's body before she realized anything.)
Joy,
Lynn
