The bike messenger was crossing 5th Avenue in the crosswalk just after 11:15 a.m. when a man driving a gray coupe pulled onto 5th, stopped abruptly in front of the crosswalk and honked at the bike messenger, according to police.
The messenger yelled something at the driver and kicked the car's wheel well, though he later told police he didn't do any damage.
Assuming the confrontation was over, the messenger continued across the street.
It was only when he reached the other side and was standing on the sidewalk that he realized the fight was just getting started. He said a passenger in the car, who he described as a pregnant woman, got out and angrily approached him.
As the screaming woman got closer, she reached into her bra and pulled out a stun gun, according to police. The messenger tried to make his getaway, but the pregnant woman gave chase and soon caught him, at which point police say she hit him twice in the face.
The male driver also got out of the car, pulled out his own stun gun and swung it at the bike messenger.
After beating the victim, the pair ran back to their car and drove away.
The messenger wasn't seriously injured in the melee and police are now trying to track down the stun-gun wielding couple.
