I'll buy any and all of those explanations, actually. Thanks guys!

Here's another mystery you can probably solve for me: When Lois has to disarm the bomb (I think in "Ordinary People"?) because Clark can't move, how come Perry's shove sends him forward? I know, Perry might hurt his hand if he shoved Clark hard enough, but Clark wasn't really looking at him, so would he have known to lower his whatever-it-is enough to allow Perry to shove him in the first place? And if he did, wouldn't Perry spraining his wrist be preferable to blowing everyone up?
