SBR Chapter 63

Seven Days in a Week is the eight hundred fifteenth chapter of the JoJo's Bizarre Adventure manga. It is also the sixty-third chapter of Steel Ball Run.

Summary
While the two are strolling down a road astride their horses, Gyro comes up with a "gag" which he presents to Johnny. He says the days of the week from Monday to Sunday in Italian. However, by Wednesday he would turn stupid, by Thursday he would make espresso (demonstrating with his hair), by Friday he would mix in the sugar, by Saturday he would drink, then on Sunday, it being a day of rest, sleep. Johnny compliments Gyro on the gag, and the two go on their way.

Trivia
