I don't know why, but there is something ineffably funny about adding "dude" to a serious quotation. "If I should die, think only this of me, dudes, there is some corner....." etc. Is it worth a short game?
[INJ] I think yours works because of the gender-bending it implies about the rest of the song. I'm gonna wash that dude right outta my hair, not so good. (However, I'm gonna wash that man right outta my dude sounds a little better.)
