屈服，用rickroll做鈴聲。因為：

Here's what happens with a rick roll...
1. You first hear it and you think it sucks.
2. The song NEVER leaves your head.
3. You have to listen to it again.
4.You start to think its a good song.
5. After a week, you love the song and have to listen to it every day!
At least this happned to me.
Copy and paste if this happened to you!!
