Every single xkcd has mouseover text. Sometimes it's just a comment on the comic, or an afterthought, but other times it's a second punchline that may be even better than the first. Now you have to go back and read them all :)
Someone at the talk at MIT asked Randall how many readers read the mouseover text, and I think he said probably less than 10%. I was surprised.
