First, post your coolest response you've ever gotten. I don't nesesarily mean your FAVORITE, but the person that sent you the coolest things.
Then, post what your ideal response would be from a celebrity.
Now, to keep it from getting continuous, try to keep away from the general:
"I wish Brad Pitt would send me a wedding ring" type of thing. I'd love Miley Cyrus to send me a letter saying she'd like to date me, but that's a bit too unreasonable.
Here's mine:
Coolest: Vanessa Anne Hudgens autographed photo and handwritten letter, which said that my letter was one of her favorites, because she usually just gets requests or letters that say OMG I LOVE YOU!!!!
Ideal: It'd have to be from Miley Cyrus, she'd send me Hannah Montana tickets, backstage passes, an autograph, letter, and do that thing where they put on lipstick and kiss the letter
