In one of my classes, I had my students blogging throughout the semester. Last week, since it was the end of semester and I reckoned everyone could use a break and do something different, I threw down the gauntlet and issued a challenge.
"Make me laugh."
Oh, that was fun.
I got Canadian cartoons and signs.
I got profane Muppets.
And I got a couple of posts mentioning this picture, which I used in during lecture twice (only twice, really).
So that's what they're referring to here and, my personal favourite, this post.
