Hamlet (h) caught a cold and in order to cure it, he follows a very strict medicine plan. He put up a rip-off calendar (今) in the anthill's kitchen which shows when he has to put a cough drop (mnemonic symbol for 含) in his mouth (口) to suck (含). The calendar always shows the right date: today (今). Hamlet made the cough drops himself out of mandarins (口).
