There’s a blonde, brunette, and a redhead all stranded on an island.
They are about 30 miles from land, and the brunette bets the redhead and blonde she could swim to land first, and if she didn’t, then she’d pay them both $100.
Well they all started swimming, and 10 miles into the swim, the redhead became tired and drowns.
The blonde and brunette continued, and about 2 miles from shore the blonde became tired, turned around and went back.
The brunette, just turned around and said what a dumbass, and never heard from the blonde again.
