Lifeguard

"You disrespectful little punk!" he yells.  The lifeguard hurls you to the floor, climbs atop the bar, and comes crashing down on top of you.

"Get 'em!"  the small man says.  "Get 'em!"

A melee breaks out in the bar, with hurled chairs, punches, and cursing all around.  You are battered and bruised.  Finally the police arrive to break it up.

"You're all headed to jail!" the fat one says.

"Whoo!  Bar fight!" the skinny one rings a bell.

You are taken to jail.  When your mother bails you out later that night, she grounds you for the rest of the summer until school starts.

Try another day in Gravity Falls.

Try another adventure.
