Teacher with rose placed in cleavage

One day the teacher came to class with a rose placed in her cleavage.

She asked, "Can anyone tell me what roses drink? How about you, Johnny ?"

"Milk!" answered Little Johnny.

"No, I'm sorry. That's the wrong answer. Roses drink water," explained
the teacher.

"Wow!" Johnny exclaimed. "I didn't know the stem was that long!"
