“That’s the other reason we wanted you two here tonight. I was hoping that between the four of us we would come up with a good story. Lois and I have been talking about it, and, to be honest, we didn’t like any of our own ideas.”
It makes perfectly good sense to me that Lois and Clark would ask his parents for advice in this matter. After all he has depended on their advice for years... even if he doesn't remember it.
