Punctuation Misinterpretation

A classroom aide was working with a small group of elementary children and she
asked, "What do you put at the end of a sentence?"
These were the replies she got:
Period.
Exclamation point.
Condom
The aide said, "Do you mean a comma?"
His response:  "Oh ya,  a comma."

I guess you're never too young for "safe punctuation."
