Just like the bad guy from Lethal Weapon 2
I've got diplomatic immunity, so Hammer cannot sue
I can write graffiti, even jaywalk in the street
I can riot, loot, not give a hoot, and touch your sister's teat 
Can't touch me!

Stop! It's Peter time
I'm a big shot, there's no doubt
Light a fire then pee it out
Don't like it, kiss my rump
For a second, let's all do the bump
Can't touch me!
Yea do the Peter Griffin Bump
Can't touch me!

I'm Presidential Peter
Interns think I'm hot
Don't care if your handicapped
I'll still park in your spot
I've been around the world
>From Hartford to Backbay
It's Peter, go Peter, MC Peter, yo Peter
Let's see Regis rap this way 
Can't touch me!

(spoken) Except you, you can touch me.
