Song Lyric Battle #1

Which is worse:

"Girl, shake dat laffy taffy, dat laffy taffy. Shake dat laffy taffy, dat laffy taffy" -"Shake Dat Laffy Taffy", D4L (but you probably only heard it sampled by Girl Talk)

or

"Are we human? Or are we dancer?" -"Human", The Killers (who are not, nor ever shall be, better than Radiohead despite Brandon Flowers' claims)

I'm not a member of the Grammar Gestapo and realize that sometimes songs sound better when you throw out the rules, but the lack of an s at the end of "dancer" bugs me. Brandon Flowers also kind of bugs me on a personal level. A quick trip to Urban Dictionary reveals that "laffy taffy" is an...err...interesting metaphor.
