The beat sounds almost exactly the same as the others (or a combination of your others), don't be afraid to try something new, challange your guitar/drummer to find a new beat.
"Ok, the line I am the Ice-cream Man, running over kids in my mini-van" is complete take off of two lines i have heard for over 6 years.
"I am the Ice-cream Man, running over fat kids in my van.
When i ring my bell, all the little fat kids run like hell!"
Now, either don't claim that line yours, or at least credit it to where it should be.
With that said, it's an ok song.
Punk isn't my forté, but music holds the same rules no matter the type.
