Mary Test and her brother Johnny Test did not want to do the Holiday Show because they thought that it might turn into a big Broadway production! Johnny said, "We do not want to do the Holiday Show!" But Yakko Warner said, "You have to do it, guys! You signed up for it! There was no backing out of it!" Mary and Johnny became very angry and caused a humongous fight in the lunch room. They picked up their cups of chocolate pudding and then they splashed it all over one of the teacher assistants! The teacher assistant was very angry! She took Mary and Johnny to the principal's office!
