The one time I was hungover, I had to go to school same as any other day. I felt rotten.

And that wasn't on purpose, either. Hattori-niichan told us it was a cough medicine.

[Hattori-niichan didn't tell you to drink the whole damn bottle after you figured out it was alcoholic Conan but that is a minor detail of course -- oh, the jug is boiling. Better get that.]
