This guy was whipping out all sorts of things for people to see.

A man on a subway platform was caught pleasuring himself on Monday before pulling out a gun when another man followed him to find out what was going on.

Police in New York City say a woman "heard a hissing noise beside her. When she looked to see what the noise was, she observed the suspect manipulating his penis outside of his pants."

The suspect started to leave and the woman, who had burst in tears, explained to another man happened. That man, in turn, followed the suspect with his phone to get video of him.

If a guy playing with his ding-a-ling on a subway platform is a New York City thing to happen, so is what happened next: the man "pulled out a black handgun, pointed [it at the man] and told him to mind his own business." Geez, you'd think he'd be a little bit more mellow after all the ecstasy.

No one was hurt (although we think there are probably some emotional scars for the woman). Police released the video of the suspect, which you can see below. Here's hoping they find and arrest the guy -- and wash their hands after cuffing him.
