Frazz by Jef Mallett. Another one of my favorites. The kid says to the teacher, "A recent poll showed teachers were among this country's most respected professionals! And I want you to know that I respect you, too." He places a hand on her back. As they walk away, the kids says, "Though I'm still partial to the guy who invented sticky notes." The teacher, with a note saying "Hottie" on her back, says, "What are you talking about?"
