This website claims to have a list of “the very best font and typography humor,” with the warning “do not click if you don’t enjoy dumb jokes about fonts and stuff.” See an example below. In the comments, the site typographunnies is mentioned, which has really bad type jokes like: “What is green and loves typography?”, answer: “Kern-it the frog.”
While I do not get this “type” of humor, this post is just one of the reasons I love your blog.
