Here is a start:

They swaggered through the jewelry store
And thought theyd have some fun
They had seen the YouTube gangstas
And like those, they had a gun
But they peed themelves
And easy money plans were soon undone
They got away with none
Run, you cowards, run away now
Run you cowards, run away now
It just hasnt been your day now
Cause grandpas got a gun
I like it. How about using “The Battle of New Orleans” as a base?
