Funny Invite/Proposal Video?

[FlyBaby]

Relay for Life is coming up within the next few months, and some of my friends on my team and I decided that we want to invite a celebrity. Not like super famous (Kate and William, the Kardashians, etc...) but still famous, ya know? Anyways, we don't know how to invite him... should we do a video? FB page? what? I'm a cancer survivor myself, so this means a lot to me. Any and all ideas would be great! And please no "he won't respond" "this is stupid" type of things. At least I'm not inviting him to my prom! This is for a good cause. But ideas/themes/other videos to take ideas from for a video would be great too. Thank you so much!!
Also, we're high school/college students
