You're doing it wrong!
This movie has so many flaws:
1. You are supposed to fire your lazer with your mouth, not like a Kamehameha.
2. You said "Kamehameha" in an unpleasant Mario/Dr. Rockso mixed voice when you're supposed to say, "IMMA FIRIN' MAH LAZER!!", like the title would've suggested.
3. The movie name should've been something like "Kamehameha animation".
4. Use YouTube for this kind of videos, not Newgrounds.
I'm sorry, but this one just isn't going to make the cut.
