Folks, this is your brain on drugs.

Innocent residents of Chicago’s Irving Park neighborhood were subjected to a horrifying incident when a seemingly drugged-up, naked man went on a wild rampage.

But not before he reportedly cut off his own penis.

That’s right, residents who were luckily separated from the obscenity yelling man by a gate, recorded the scene as he gushed blood from where his penis used to be.

It didn’t take long for Chicago Police to arrive, and like a raging bull, the crazed man charged.

“Oh my God, bro. Shoot his a**,” a man yelled to the Chicago officers. “Shoot that mother f****r. This is a time when you shoot people!”

Officers kept their cool and tasered the naked man instead, but it didn’t take him down for long.

Police were forced to tase him a second time after he got up again to the shock and amazement of horrified onlookers.

That is where the video that has been uploaded to social media ends. There has been no further reports on the identity or condition of the man who was tasered.
