Leave My Reef, Laughing

You are a clownfish.

The reef you live in has suddenly become a popular diving spot.
Your task is to get those pesky diving humans to leave the reef. Use several objects scattered around the reef to create humorous situations which make the humans laugh.
The humans will lose air every time they laugh, which will cause them to eventually return to te surface. So swim around, create spontaneous jokes and make the humans leave the reef, laughing!
