The Bad Boy in the Plastic Bubble

The staff has to come in for half a day to take a seminar on proper waste disposal because Jack's been throwing hazardous waste in the regular trash bins. Jack, as a ""volunteer,"" worms his way out of showing up, and rubs everyone's noses in it. So Luke tells Jack that he may have been contaminated by a toxic substance, and cons him into spending time in a plastic bubble... wearing only a diaper. Meanwhile, Annie's hawking chocolate for her son, and Hank agrees to buy two cases – but he can't even afford one bar.
