Graduation thank you party?!!?

Heyy, so today I was with one of my teachers discussing plans for upcoming fundraisers not only the student council will be doing but the cles and staff members as well! The faculty in my school is by far unbelievably talented and just the biggest sweet hearts. I've never meet anyone quite like them! Now my problem tradition does not seem to work to well amongst the students in my school. I thought it might be a good idea to have a dinner//banquet//something to give the teachers recognition they deserve! DOes anybody have any ideas that we can come up with?!?!?
