Chang’s World, APO magazine edition 790, 1 April 2015.
Since comic not in English, I’ll translate it.
Strip 1 : Doctor said “Ok, i’ll start the operation on this patient’s stomach”
Strip 2 : oh my god!!!
Strip 3 :
Male Nurse 1 : what’s wrong?
Doctor : “you guys, just stitch up back this patient” while looking back,no eye contact
Male Nurse 2 : “is it that the patient could not be saved?” : looking worried
Strip 4 :
Doctor calmly answers, “nope, just the wrong patient” with everybody flipping back down in the background like Shin Chan manga / Japanese anime when unexpected silliness occurs.
