It's become a Western Homecoming tradition, a sea of students fill Broughdale Ave. just south of the university.
But the students insist it's all good clean fun.
In the last two years there have been concerns students have taken the fun a little two far but students say that message has been recieved.
"We're controlling the situation here. No one's getting out of hand. We're having a great time," says student Denver Scott.
Still, police, the University and the Western Student Council have stepped up efforts to keep things in check.
It starts with a heavier police presence.
Officers had to deal with public consumption of alcohol, public urination and trespassing.
Most students say the have no problems with the way police have handled the situation.
"I do think they should regulate it which is what they're doing. They're doing great. They're not being offensive in terms of ticketing people that shouldn't be ticketed. Everyone's going to be doing it," says Izzy lazarova, Western student.
London police Inspector Bill Chantler says the behaviour of students has been noticebly better this year.
"The difference between a good day and a bad day is attitude and I can tell you we're having a great day," says Insp. Chantler.
No sooner had he said that, he spotted a party-goer throw a can into a crowd of people and the man was immediately taken into custody.
Chantler says anything that may incite violence won't be tolerated.
"Our primary objective, our primary goal here is to keep everyone safe," he adds.
The university did its part trying to keep more students on campus and off of public streets, adding a morning concert which drew about 7000 students.
All parties will sit down next week to review how Homecoming events went.
