How would one get a lot of people together at once?

Question by hello: How would one get a lot of people together at once?
I need 15 to 20 people to be in a music video I’m making for film making class. The problem is, I don’t know how I would get them all together at the same time (rides, motivation for them to come, etc) It doesn’t really matter who they are; I just need extras.
Any ideas?

(I know this doesn’t really have to do with P&S but I know a lot of people come here…)
Thanks!

Ask them to stay after school one day. A friend of mine that I worked on the music video did that.
