From Byron's Don Juan:
Here Lolah interposed -- "Mamma, you know
You don't sleep soundly, and I cannot bear
That anybody should disturb you so;
I'll take Juanna; we're a slenderer pair
Than you would make the half of; -- don't say no;
And I of your young charge will take due care."
But here Katinka interfered, and said,
"She also had compassion and a bed.
What is the meaning of we're a slenderer pair than you would make the half of?
When we lie together, we take up less than 50% of your width?
