SF State students came, they saw and they partied on Muni for a class project Thursday night.

Brianna Quintero and John Espiritu, both communication majors, organized a moving party aboard an M Muni train as part of a class project in orchestrating a "flash mob," said Espiritu.

Their project goals were to create an extraordinary event in an ordinary setting along with having reactions with actions, said Quintero.

"We wanted organized chaos," Espiritu said before the party began on the train. "We want to have fun and make sure everyone has a good time."

The "flash mob" started moments before the 7:17 p.m. train came into the station. Once the train opened its doors, over 150 students and four out of 10 San Francisco police officers crammed into the inbound M on their way to Montgomery Street station, with a 21-and-over after-party scheduled at the Otis Lounge in the Financial District.

The students chanted and sang through all 10 Muni stops towards Montgomery Street station. Chants of station names were made at every stop along with chorus' sang of popular songs from "Paradise City" by Guns and Roses to "Anyway You Want It" by Journey.

The event was created via Facebook and originally had 140 people invited, but right before the party took place, there were over 1,800 people invited, said Quintero.

The term "flash mob" is used to describe the disruption of the ordinary flow of things in public places, said Espiritu.

Espiritu, 22, who came up with the Muni party idea, added that in the current economic tribulation, it's important to have people enjoy themselves and have fun in cheap and interesting ways.

"It's fascinating," said senior James Roscelli. "I never thought so many people would want to party on Muni."

The San Francisco Police Department showed a strong presence on the SF State Muni station and on the train itself.

"We're here to make sure everyone is safe," said SFPD officer Tim Gibson. "We don't want anything harmful to happen tonight."

Quintero, 22, added that she did not encourage drinking on Muni, which is why there was an after-party at a bar one block away from the Montgomery Street station.

"We're not responsible for the people that party with us," Quintero said. "They're on their own."

Quintero adds she plans to have further "flash mobs" in the future.

"We have plans to have people dress up in Super Mario Bros. costumes and play tennis on the tennis courts like in the game Mario Tennis," she said. "This isn't the end."
