So one day little Johnny goes into the kitchen and says to his mom, "Mom, grandma's got her shrimps hanging out again."
Knowing that the grandma is going a little senile in her old age, mom goes out into the living room and finds grandma sitting in her lazy-boy with her dress up and her panties around her ankles.
Not knowing how she is going to explain this to her son, the mom goes back into the kitchen and says to little Johnny, " Honey, those aren't shrimps. They are part of the vagina which is the female reproductive organ on a woman, just like the penis is for a man."
Little Johnny replies, "Well whatever you say mom but they sure taste like shrimps to me!"
