First off, you will need at least level 50 sneak skill, and level 36 speech. But if you don't have that, these items will help you:
A machine gun
A black ski mask
Step 2: Getting In The DMV
Step inside the dmv with your lunettes edition Micky Mouse strap sandals and get your gun ready. And make sure your mask is tightly secured! You don't want Tim Allen coming through and ripping it off with his Croc brand handy man gloves!
Step 3: Approaching The Clerk
Approach the clerk with brutal force, yelling intimidating words like "monkey seals", and "cottage cheese crocs".
Step 4: Getting Your Permit
Yell at her to give you a permit, and throw whistles at her. If she doesn't obey, you're going to have to do something drastic
Step 5: Drive
And finally; start driving! You're ready to get behind the wheel and start running over windex bottles filled with Dawn Soap!
