A son whose no-nonsense dad gave him a fitting punishment for being a bully - and sent his story viral - has seen the error of his ways . Kayden Robenhorst , 13 , said 'thank you , I deserved that ' to dad Timothy , who surprised him with a run , 60 push-ups and gardening chores at 4am in freezing Green Bay , Wisconsin , after finding out he 'd been mistreating a classmate . A photograph showing Kayden and Timothy posing with a sign explaining his sentence has been shared thousands of times online . Spelling it out : Timothy Robenhorst was shocked to heard his son , Kayden , had been bullying somebody at school - so devised the above punishment for him . Just desserts : Kayden , 13 , is pictured above in the midst of a 'knuckle push-up ' , part of his grueling punishment . From above : Kayden said of the punishment ' I learned my lesson , and he 's a good dad for doing it ' Another condition of the punishment is that it remains Kayden 's own Facebook profile picture and cover photo until Robenhorst relents . The surprise punishment , carried out Wednesday in 32-degree weather , came after Timothy got wind that his son had insulted a classmate , and later pushed him into a locker while walking between classes . Robenhorst , who heard what had happened from friends , decided not to let his son know in advance , but sprang the punishment on him at 4am . Punished : Kayden , pictured , was given an array of unpleasant tasks to make up for his wrongs . After sitting him down and explaining what was about to happen , he dressed him up , stood over him during the push-ups then sent him out on the run . Describing the experience to DailyMail.com , Kayden said : 'It was stupid of me - I saw a kid and said a stupid , random comment . ' 'When he found up , he woke me up at 3:30 in the morning , and he sat me down on the couch . And when I did n't come up with a good enough excuse to save my butt , I told the truth . 'He made me do 50 knuckle push-ups , run a mile , then come back and do incline push-ups . And I 'm still not done . ' ' I think it 's a really good punishment - I learned my lesson and he 's a good dad for doing it . ' The two planned to have Kayden apologize to the boy in question in front of his whole class , but school authorities decided a private meeting would be a better solution . Kayden also apologized a second time when there were no teachers and parents around . Speaking about his high-profile parenting , Robenhorst said : 'He understood - he knows it was wrong and there have been no hard feelings since . ' 'He actually has said `` Thank you , I deserved that , I understand it was wrong . '' I believe he also apologized to the child another time the other day . ' 'He did n't question his punishment - he had a look on his face , you can see he was n't very happy when he was getting his picture taken - but it 's been successful . ' 'And seeing it go around the way it 's been going around - I would do anything to put this out there and say `` Hey , do n't let your child get away with this crap '' . Even small bullying can turn into something big . ' Apology : Kayden was made to say sorry to his victim in front of his whole class at Pulaski Middle School , pictured . Kayden , who lives with Robenhorst , who is a business consultant , and his wife , used to live with his mother in South Carolina , where he had a difficult past . But his father said he has seen him transform since coming north , and is now doing well at Pulaski Middle School . Under the original post , Robenhorst had written : ' I teach my kids they do not start fights but if someone puts their hands on them they finish it . 'This is what happens when you become a bully ! I do n't put up with it and at 4:30am today my son found out what happens when you pray on people for no reason and bully ! 'Please share this to end this behavior everywhere ! Nothing changes until you take a stance and it only takes one person to start a revolution ! ' Kayden concurs , adding : 'It 's a good message and I hope lots of people see it ' .
