It's Mac-ademic - S3.E13

Bernie doesn't like it that Bryanna's education consists of playing in the sandbox, tag and tiddlywinks, and he begins to question the teaching methods at the Wellington School. So Bernie volunteers as a teacher's helper for a week to see for himself. Things go wrong from the start when he demands respect from the kids and asks them to call him Mr. Mac instead of by his first name, as they do with the other adults at the school. When he gets resistance from the kids, the teachers tell Bernie that since he does not respect the Wellington way he must be on his way. He takes Bryanna with him but enrolling her in a new school isn't as easy as it seems. Meanwhile, Wanda thinks she can reason with Vanessa and Jordan and resists using violence against violence to get them to stop fighting, but she's beginning to think it's the only thing that will work.
