This video is seriously awesome...and gives some great ideas!

It's the ultimate compilation of people waking up other people via pranks. The first one is definitely our favorite.

It's a guy who pranks awake his friend by setting up a pool next to the couch. Then, he moves the couch so she falls off and into the pool. Instantly awake! HAHAHA

Most of the other ones involve the prankers scaring their friends awake, not as creative but just as funny.
