Skipping Out Can Be Hazardous

When you ate at this restaurant yesterday, you left without paying.
I have my shotgun behind the counter, you'd better start praying.
Last week another customer tried to pull the same crap.
I pulled out this shotgun and now he has no knee caps.
You skipped out on your bill and you have the nerve to come back.
When it comes to the brains department, it's something you lack.
You're trying to get out of here and you're moving fast.
But not quick enough, I just put a buckshot up your ass.
Now you're spilling blood on my nice clean floor.
Hit the road, Jack and you'd better not come here anymore!
