Writer's Block

So recently I've been having a bad case of writer's block. This is for my youtube channel, BarnieAndFrenz ( http://youtube.com/BarnieAndFrenz ).
I have found it becoming increasingly difficult to come with new material for my videos. To make matters worse, it's finally summer and I can't come up with any video ideas. All throughout the school year, I kept saying to myself that I would make a lot of awesome videos during the summer.
Now, that time has finally reached and my ideas have run dry.
Fortunately I was able to film one today and I already edited and uploaded it. It's called "YO MAMA". I am awaiting the feedback from my subscribers. One thing I find though, is that alot of my subscribers don't actually watch my videos. They're either people who subscribe to alot of people for their own publicity, or people who hardly ever log on to Youtube.
However, my cousins are coming down to spend 6 weeks so hopefully we can pitch together ideas and make good videos.
