(Strip Number 1224, Original Publication Date, 10 November 1987)
Panel 1: Now that Mike's washed his face, Gordon tells him that he's not exactly 'green' now. Mike wants to know what he exactly is.
Panel 2: Gordon says that he just looks as if he's a bit sick-looking.
Panel 3: When Mike balks at having to look as if he's going to throw up, Gordon asks why.
Panel 4: After all, he can easily blame the cafeteria and avoid censure.
Summary: As I said, it's not the kids Mike has to be really worried about. What he's got to worry about is a male version of that idiot Miss Blais publicly shaming him.
