Shock Collar Question – June 29

Brooke is wearing the Shock Collar this morning!

Today’s question: In 1916, a battle between the Irish Army and British Forces was taking place in a downtown Dublin park called St. Stephen’s Green. Both armies were stationed on opposite sides of a man-made lake and tensions were high. While there was gun fire for almost an entire week between the two groups, the forces did agree to a cease fire for one hour, once a day, for one particular hilarious but necessary reason. What was it?
