Well, in retrospect, the khaki pants were an unfortunate choice.
We're not sure if Liam Neeson simply spilled a drink during dinner, was playing a prank on paparazzi or has been taking a little too much inspiration from Gérard Depardieu, but whatever the cause, the venerable Irish actor emerged from London's chi-chi Scott's restaurant and seemingly appeared to be none the wiser as to the rather prominent wet patch that was smack dab in the most unfortunate of regions: his crotch.
In any case, the 59-year-old actor was either oblivious or unbothered by the suspicious spot as he exited the eatery, going about business as usual as he exited the eatery, shaking hands with fans and not even bothering to zip up his jacket (which surely would have provided him a little more, um, coverage).
We may never get to the bottom of this mystery. But hey, what's a wee small stain between friends?
