Because one more would be too farty
You would too if you were a ginger
One wants to stay drunk all the time and the other doesn't want to pay the tab.
Because one more would be "two-fahrty"
Because one more, and it'd be too farty.
If there were one more it would be two-farty!
If they had one more it would be to farty
Because if you added one more it'd be two farty.
Because just one more and it would be two-farty
