Sheep...? CHEAP!

My oldest daughter, L, was looking for a snack to take to school this morning. The coversation is as follows:

L: Can I have some string cheese?
M: Yes
L: Is it the kind with jokes on it?
M: No, it's the cheap kind.
L: Sheep? I don't see no sheep...
M: (ROFL) No, CHEAP, inexpensive, not SHEEP!!
L: Oh (crestfallen look)

Thank you, dearest L, for the morning giggle.
