It's like that episode of Everybody Loves Raymond where Ray's mom (Marie Barone) creates a sculpture that looks like a womb area, and only Ray and his wife can immediately see the ... hidden image, and Ray's dad (Frank Barone) for some reason is very drawn to the sculpture and he can't quite put his finger on it. After Ray, lets his mom know, then she can't unsee it.

Hilarity ensues.
