Ideas for a fun celebration for a colleague who is retiring...

Hi folks! this is my first post on this forum, and before I start I just want to thank everyone who has participated in this forum. I find it to be informative, funny, and the topics here are ones that I can absolutely relate to!

And now to get to the meat of the matter; I have a colleague who will be retiring next year, and I am wondering if any of you have any ideas in terms of how to celebrate her retirement. It will most likely be a HUGE dinner get together with at least 50 people attending. I would like this to be a fun/memorable event , and am wondering if anyone has ideas of things we could do... What kinds of things have you done to celebrate a nurse who's about to retire...this person has been nursing in long term care for 40 years, she has a great sense of humor, so we want to send her off with a party she won't forget...any ideas that you have would be greatly appreciated , ( no matter how bizarre)

Much Love!
