Tourists who wander along the closed-off stretch of Pennsylvania Avenue opposite the White House should, in theory, be used to seeing some pretty off-the-wall stuff.

Tuesday proved no exception.

“Look! It’s a BUNNY!” shrieked an out-of-town teen (the matching, dayglo t-shirts are a dead giveaway) — who will most likely return home with an Instagram feed chock full of pics of locked gates, barricaded monuments and traffic barrels festooned with yellow tape — upon spotting the sign-wielding character parading around outside POTUS’ pad.

The costumed crusader told HOH he was making the rounds to raise awareness about Purge Day, a fledgling movement that challenges everyone to unburden themselves of all negative thoughts once annually (next official observance: Aug., 20, 2014).

Apart from spreading the word, the corresponding website also amasses funds with which to aid troubled teens via the sale of creepy looking “Positive Bunny” totems.

We must admit, our innate cynicism and years of MTV viewing initially led us to believe the well meaning giant rabbit was almost certainly there to punk tourists or promote some underground film project.

But then we remembered that, at least in this town, the real crazies sport business suits and lapel pins.
