i love mr. plaag i think he just having some fun when he makes fun of kids sometimes. he doesnt mean it in a bad way he's just joking. it makes me laugh and he was an awesome teacher.
Mr. Plaag is the best science teacher I have ever had. Although sometimes he does seem like he is talking down to students, his unique way of teaching helped me to take away a lot from his class.
this just in plaag- we're not really retarded, we just see your class as naptime
