"Create an image of a teacher standing at the front of a classroom, wearing a shirt that proudly declares 'I love my job' in bold letters. However, the humor comes from the fact that the teacher's face is a crudely drawn angry face, complete with a scowl and a furrowed brow. The teacher's posture and body language convey a sense of frustration and annoyance, as if they're about to explode. The students in the background look on in amusement, some of them trying to stifle giggles. The contrast between the teacher's cheerful shirt and their angry expression creates a comedic effect. The image should be rendered in a humorous and exaggerated style, with bold lines and bright colors. Think 'cartoonish' and 'playful'. "
