Montgomery County police did the unthinkable last week: They pulled over Batman for driving without properly fastened license plates.

But who is this Lamborghini driver who dispenses vigilante justice but can’t be bothered to follow the rules of the road?

Turns out, he’s a buddy of the Post’s Maryland blogger Michael Rosenwald. And for all of Batman’s moving violations, he’s actually a good guy who sends his time brightening the days of sick children in area hospitals.

However, his real name doesn’t convey the same steely resolve as “Bruce Wayne.” This Batman’s true identity is Lenny B. Robinson, and he invited Rosenwald along on Monday to Children’s National Medical Center as part of his work for the Hope for Henry foundation:

On Monday, he pulled up in his black Lambo with yellow Batman symbols on the doors, the floor mats, the headrests — pretty much everywhere — and he was dressed in his heavy leather and neoprene uniform that he bought from a professional costume maker.

He carried two large bags of Batman books, rubber Batman symbol bracelets and various other toys up to the front desk, where the check-in attendant asked him his name.

“Batman,” he said.

…

Batman asked each child his or her name. He lifted up almost every child. Many were weak, their hair thin from chemo. He always told them, “I have a present for you.” When a little girl ran away, perhaps a bit scared, Batman said, “That’s the story of Batman’s love life.” (He is divorced.)

Batman overheard a mother tell someone that her toddler was going home the next day, and holding the toddler, and hugging him gently, Batman said, “I’m really glad you are feeling better.”

Although there’s no audio with Rosenwald’s post, we’re going to assume that Robinson’s Batman sounds more like, say, Adam West than any of the more imposing cinematic Batmen. Christian Bale’s Cookie Monster vocals don’t exactly seem appropriate for the pediatric ICU.
