MICKEY Rourke must have had an epic Monday night. Yesterday at 1:45 p.m., the star of “The Wrestler” was asked to pose for photographers in front of the W Hotel’s lounge at the Bryant Park tents. One lensman repeatedly asked Rourke, “Smile! Why aren’t you smiling?” — to which Rourke slurred, ” ‘Cause I’m still drunk.” Discussing his own outfit, Rourke said, “I’m wearing the same suit I got from a bad movie I did seven years ago. It’s still got the stains from a bullet hole. I just put this colorful pocket square in front of the stain so nobody can tell.”
