This is the first episode of Timmy being grounded.
Timmy's sickness is fake! Initially, Shaun fakes being ill to stay in the barn and enjoy his secret hideout, but Timmy eventually discovers the ruse and decides he also wants to skip a day of work. To trick Bitzer, Timmy uses makeup to create red spots on his face so he can pretend play sick and join Shaun in the den.
