the principal is the pauper: insult chalmers at your doorstep.
ruined roast: tell chalmers that the roast is on fire.
time paradox: tell chalmers you actually did just get krusty burgers.
alien tamzarian: tell chalmers you must go now... your planet needs you.
unforgettable luncheon: let chalmers view the northern lights.
