Dumb Teachers was a comic strip that was submitted as a comic for the school newspaper in Diary of a Wimpy Kid. It shows Mr. Ira, who had just pooped in his pants, and two students who are pointing it out to him. It was created by a kid named Bill Tritt, who is supposedly sent to detention all the time. The girl from the comic also appears in Do-It-Yourself book in one of the pages where you write your own book.
- This comic was rejected because it was slandering and might offend teachers like Mr. Ira.
