Mr Meaner is the gym teacher at the Jerome Horwitz Elementary School. Like Benjamin Krupp and the rest of the school staff, he is nasty and hates children, especially George and Harold. He is usually cruel to the students who aren't athletic. In George and Harold's comics the teachers care little about him. His name is a pun on the word "misdemeanor", which refers to a crime much less serious than a felony such as a theft.

He is the main antagonist Sir Stinks-A-Lot for Captain Underpants and the Sensational Saga of Sir Stinks-A-Lot.
He is voiced by Fred Tatasciore in the film Captain Underpants: The First Epic Movie.

Mr. Meaner then reflects on how their problems were caused by the students at the school. So he gave a command that they all return to the school immediately and act like nothing has happened out of the ordinary and nothing to look suspicious.
Few days later school classes resumed on a normal day basis. Nothing unusual happened not even Mr. Krupp himself got into the trance of becoming Captain Underpants. But later on that night Mr. Meaner was in a makeshift laboratory getting his evil plans in order by using stinky sweaty socks along with chemicals and formula and some ingredients.

After leaving his Office due to 30 minutes pass, the yesterdays version of the boys showed up late to class but were not as they seemed as if Mr Meaner put them in a trance that causes them to never misbehave have fun or day dream using their imaginations. They were later confronted by Ms Anita Calculator but they didn't show any signs of whining or becoming worried by being acceptive of what she was going to do to them no matter how bad it could've been. She then found the boys on their best behavior not being disruptive at all which had Melvin and other students confused of them. Melvin didn't know what was going on at this time but he was impressed. the yesterday boys didn't even change the letter of the signs. At the end of the day, Even Mr. Krupp didn't punish the boys for good behavior but accepted it as they walked off. Mr Meaner tells Mr. Krupp that this was only the begin as he patted him on the head.
Later on that night and while the present version of George and Harold were confused to whats happened to their past counterparts. Mr Meaner made some more adjustments to his invention and named it the Stinky-Kong 2000 (parody of Donkey Kong the ape). Mr. Meaner turned his invention into an ape like suit and caused his reign of terror upon the students of the school causing them to behave well and never have any kind of fun or play but only work and work only and did as they were told by the teachers and principal. The present boys George and Harold were affected and sick and tired of the homework they have done every time give but their hypnotized yesterday counterparts. They later discover that Mr Meaner was on TV advertising a stinky product to use on misbehaving children.
As the present boys are sickly trying their best to get to the bottom of this disguising themselves as adults, they realize that the children who are being well behaved have now became slaves to the staff of the school doing their bidding they the staff commanded them to do. Present sick George then had plan and he and Harold commanded the children to what they told them to do by flipping everything around by causing the pranks to the staff and teachers. Later on the teachers noticed what has happened to them such as hair being cut, faces drawn on to them, and clothes cut.
Mr. Krupp then comes to Mr Meaner informing them on what the children have done. So Mr Meaner then gets to the bottom of what has happened. He then flees the school getting into his cottage cheese filled car driving angry to find out who could have done this to the teachers. He came across a group of kids in the trance who were watering the inside of the house, mowing the garden and painting the lawn. he ask them who told them to do all those things and all the children could say was a grown up but didn't say who the grown up was. Mr meaner rushes back to the car angry and drive off back to the factory going to his invention with new modifications. He feels that a kid has caused this but he doesn't know who the kid is.
Later he returns in his ape suit causing havoc in the town of piqua unleashing the foul odor everywhere. Present Harold and George who are still sick witnessed what was Mr. Meaner was doing however they couldn't smell so the stench have no effect on them however Harold and George were almost better and that wasn't a good thing so they went to their parents who were having dinner with their yesterday counterparts.
