I did, and the primary hit was good ol' Snopes, where there was no Snopes article on it, but there was a forum discussion which seemed to indicate an Internet-born quote that had taken on a life of its own. Another was something I hadn't heard of, "metabunk.org," which also said it wasn't real and backs the debunking up pretty well.
I don't want to rain on parades, much, but I mean, I remember Kennedy and would be surprised if I've lived this long and not heard this one before.
