This came to me yesterday, ^^

The cameras hadn't been in Light Yagami's room for long. Now that Light knew that there were cameras and bugs in his room,
thanks to Ryuuk, he had his plan.

Light went over his plan in his head."Just watch me, L. I'll solve equations with my right hand, and write names with my left.
I'll take a potato chip...and eat it!"

Light knew he was brilliant.

"Yagami-san, how long will this family outing last?" asked L. He was concerned about Light, his suspect, being away from his room. If Light Yagami was Kira, he might be able to kill during this family outing. L had to make sure he was under surveilence at all time.

"Um...a few hours at the most. Why?" replied Soichiro.

"I would like to put a bug on you so I can hear in on all of your conversations, and keep an eye on your son, Yagami-san,"said L,"
so I have prepared a shirt that has a bug in place in stead of a button. There will also be a camera." L gave Soichiro the shirt to wear later that evening.
With that, Soichiro left to go home.

Soichiro wore the shirt that L had given him. The rest of the family,except for Light, was oblivious to the fact that there was a bug,along with a camera, planted on his shirt. They all liked it though.

Light was amused with the fact that L had made his father wear a shirt with a bug and camera on it. He can't be caught that easily.

L watched the screen. The Yagami family had just arived at the resturant. "Light Yagami is smirking..." L said to himself.
It was true. Light was smirking as he went over his brilliant plan in his head over and over again. He kept saying it over and over again,
even when the food got there. He started laughing quietly.

"Light Yagami appears to be laughing..."

Light all of a sudden jumped out of his seat and ran all around the resturant.
He then went back to his plate and violently stabbed a piece of beef. The rest of the family just stared.

"I'll take this beef...AND EAT IT!" Light ate it.

"Well isn't that what one does with beef, Light Yagami?" said L to himself.

This continued for the rest of the evening. Even after they got home, Light raided the pantry for things to take and eat. L was easily amused.

"Yagami-kun, what was that episode yesturday evening with the beef?" asked L.

"Ryuuzaki, I dont know. It just...happened..."replied Soichiro.

"Of course, Yagami-san. I am going to continue surveilence on your son, especially after that outburst."

"Of course, Ryuuzaki."

"Hey Light?" said Ryuuk.

"Yes," replied Light after he made sure no one was watching.

"I'll take this apple...AND EAT IT!"

Light just glared.
