We've all known that somebody has had some 'splainin' to do since the release of the Mitchell Report more than two weeks ago.

Now, here comes this weekend's edition of 60 Minutes and, judging from the early teases, what we're about to get from Roger Clemens is ... a Barry Bonds Moment.

Lovely.

Yes, Clemens told CBS News' Mike Wallace trainer Brian McNamee did inject him. With lidocaine and B-12.

"It's for my joints, and I still take B-12 today," Clemens tells the program.

What, no flaxseed oil?

Come on. Two weeks of lockdown, aside from Clemens' lame Internet video denying everything that was downright, disingenuously Clintonesque in its manner ("I did not have sexual relations with that woman"), and this is where we are?

Some folks take over-the-counter glucosamine supplements to combat creaky joints as they age ... and Clemens takes injections in the butt?

Look, nobody is casting any final judgments here, and yes, elite athletes are going to use, let's say, a higher-octane fuel to protect their bodies than the rest of us weekend warriors.

But if Clemens thinks that this explanation is anywhere close to being enough to topple the tower of circumstantial evidence built against him in the Mitchell Report, then he hasn't used his time very wisely in these past two weeks.

Essentially, as McNamee's lawyers circle and threaten lawsuits if Clemens tells 60 Minutes that McNamee was not truthful, what we've got is this: The former trainer and Clemens both agree now that McNamee injected Clemens.

But they differ on exactly what substance was in the needle.

Now. McNamee obviously was providing a service to players based on his testimony, a service that the owners chose to ignore, and he isn't exactly a saint in the city in this caper.

But do you honestly believe that any licensed trainer would inject the elite athletes he's paid to take care of without quite knowing for sure what was in the syringe?

The choices in this weekend's 60 Minutes segment of he-said, she-said, based on where McNamee and Clemens now stand, are pretty clear-cut:

A. McNamee injected Clemens with steroids, both men knew it, and one is lying about it now.

B. McNamee injected Clemens with lidocaine and B-12, both men knew it, and one is lying about it now.

C. McNamee injected Clemens with something but really wasn't sure what the hell it was.

Flaxseed oil, perhaps?

What it sounds like is that Clemens is going to be peddling some snake oil Sunday night, and the fear here is that Mike Wallace, once one of America's great newsmen who is an admitted Yankees fan and a frequent visitor to owner George Steinbrenner's private box in Yankee Stadium, might be all too eager to buy.
