Touhou 4-Panel Strips #1687 Medicine One Can Give
Now making emergency transport...
[Survey: What medicine can you give a ⑨?]
• Oral medicine
• Eye medicine
• Apply a compress and leave them like that
• Liniment
The title comes from the axiom 馬鹿に付ける薬はない—literally, "There is no medicine one can give to a fool". More idiomatically, "A born fool is never cured" or "There's no cure for stupidity."
