Oh really, O'Leary? Pay to use the loo?

Okay, we didn't bite the first 27 times that Michael O'Leary mouthed off about how he was serious about charging passengers on his Ryanair to use the on-board bathrooms. We figured it was just more O'Leary playing up to the 'Michael O'Really' role he loves so much. But now the man insists he's for real.
Fresh off posting Ryanair's first annual deficit since the carrier went public a dozen years ago, O'Leary tells the London press that he is deadly serious about having a credit-card reader placed on the lavatory doors on Ryanair's 737-800s. After all, he reasons, most Ryanair flights are only about an hour, so people ought to be able to hold on for that long. What we worry about is holding a straight face...
(A little post-script, just to be fair: Ryanair lost money because of its attempt to takeover Aer Lingus; it actually made an operating profit. That's still no excuse...)
