That is funny.  I have not heard this but I'm assuming it had to be a wife.  I'm with NuraB I also think it might be Ayisha.

JazakAllah khayr for your responses sis Nura and Br.Duane.

She was Saudah Bint Za'mah RA who was the first wife of Prophet to be married after the death of Khadijah RA.

Here's an other incident about her which i love reading always

When Saudah first heard about the Dajjal from the Prophet she was terrified. Being the simple person that she was, it became a hobby for the others to talk about it and frighten her and then laugh at her. On one occasion 'Aishah and the Mother of the Believers Hafsah started talking about it in front of her. She was so scared that she immediately ran into a dark room full of cobwebs to hide from the monster. When the Prophet Muhammad walked in he found the two enjoying the joke. He asked them what was so amusing. On being told what had happened he called out to Saudah to come out as there was no monster around. She came out sheepishly laughing at herself.

On one occasion, the Prophet `Aishah and Saudah were sitting together and chatting. The former cooked a special dish and offered it to the latter. But she declined. 'Aishah was a lively young person, and threatened to force feed Saudah And when she continued to remain serious, she actually splashed it all over her face! So this lighthearted gaiety and spirit of camaraderie was very much part of the Prophet's household. There was no malice and jealousy in this pure atmosphere. It was reflective of the pleasant ambiance in the household of the Prophet where there was always a loving concern and affection for all
