Gretchen just returned from the beach, and told her brother Henry that she found three interesting types of shells. He asked what they were, and she answered with these rebuses:
LL

AA
CC
SS
- Nice Naughty Nice Naughty
- Naughty Nice Naughty Nice
*3. Nice Nice Nice Nice
After thinking for a while, Henry says, "I get the first two types of shells, but didn't you say you found three?"
"Oops! I almost forgot!" replies Gretchen, as she hits her brother on the head.
"Now I know them all!" he laughs.
