YouTube!!

I made a YouTube account! Yeah! But I'm too shy to reveal it yet.....so until I make more videos, yeah, it's a SECRET! haha. So anyway, I'm thinking, what videos should I make? Please give me tips! Thank you. I plan on making silly videos....but I have a hard time using the mask tool at sony vegas! Like how do you move the mask?? It is sooo hard! I'm wearing my Hannah Montana jammies today! Woo hoo! ^^. so yeah, what videos??
