Little Rivka is talking to Naomi, her best friend. "My mom just bought me the latest Barbie doll for my birthday. And it's a Jewish mother Barbie doll."
"You're so lucky!" says Naomi. "So what does the doll do?"
"When you press her belly button," replies Rivka, "it cries out, 'Oy Vay, enough with the belly button already.'"
