What a great life lesson huh? Also before I start the other day I was looking at gravity falls pictures and I found the perfect one for Bryanna:

Mabel's kid for sure, anyway lets get started with this scrip based chapter.

Today Mabel's guide to....PROM!

Mabel: Ah its that time of year where we have the annual school dance that pretty much destroys our bank accounts and max out our credit cards, PROM!

Candy shows up blowing a noise maker.

Mabel: So today I got some tips on how to make your prom night extra magical.

Step 1: The Ride.

Mabel: Everyone needs a lift somewhere, but for prom you gotta go in style. There are multitude of ways to get there.

Way #1: Personal Driver.

Mabel is Seen in the back seat of a car.

Mabel: Okay Turn Left, no Left, no Left, Don't you know left from right?

Camera moves to the front seat show Bryanna pretending to drive the car and make noises.

Bryanna notices the camera.

Bryanna: Hi!

Mabel: This is what I get for not finding an actor in time.

Way #2: Limo.

Mabel: The limo is the traditional way to get to prom, but sadly me and my Posse are using the 3rd way....Did I really just say posse? Never again.

Way #3: Party Bus!!!!!!!!

Mabel: Anything with the word party makes anything 100000000000000× better! Plus its great for those #SquadPics!

Step 2: The Dress:

Mabel: Every Girl has to Dress *Snaps* To Impress. Put unfortunately my dress is all white and all white is both boring and unsuitable because its after labor day. Or is it before, anyway, since I made this dress, #StitchingPro, I decided to add some color, luckily I know someone who is willing to help.

Hey BryBry!

The dress is shown with a ton of Different colors.

Mabel: That was both a good idea and a bad idea at the same time.

"Well I like the little publicity you gave me at the end," said Xander.

"Hey anything for my sweet guy," said Mabel.

She then kisses his cheek.
