Rare disease

Old Mendel Rugelbaum was very old and suffering from a rare disease and could drink only human milk.

"How can I get human milk?" Mendel asked the doctor.

"Well, Ruby Finkelstein's just had a baby, maybe she'll help."

So every day Mendel went to Ruby's house for his daily feed. Ruby was a dark-eyed, big breasted lady, who, in spite of herself, gradually became aroused as Mendel lapped at her ripe breasts.

One day as he quietly lay sucking, she whispered to him, " Tell me Mr. Rugelbaum, do you like it?"

"Mmmm, wonderful," he sighed.

"Is there....," she hesitated, her lips parted, eyes aglow, "is there anything else you'd like?"

"As a matter of fact there is," murmured Mendel.

"What?" Ruby asked breathlessly.

Mendel licked his lips. "Maybe a little biscuit?"
