The British House of Commons keeps its parties separated by an aisle, which is one of the origins of the phrase "crossing the aisle."

When someone steps into the aisle to confront an opposition party member, the man in charge will call out "Toe the line!" which is also the origin of that phrase.

The aisle has an official defined width.

What is the official defined width?

"Two sword lengths plus one foot."
