Because if there were one more, it'd be two forty. (Too farty) This works much better when spoken out loud. The joke how Irish people pronounce "forty."
Because if you add even one more it gets "2 farty".
Because one more would have been too farty.
Because one more, and it'd be too farty.
Because one more would be "two-fahrty"
Because just one more and it would be two-farty
Because if they had one more, they would be 240.
