A simple solution to a complex dating dilemma: Joe asks Cindy out on a date. Cindy agrees on the condition that Joe will find a date for her mentally retarded cousin Patti. Joe hasn't gotten pussy in 972 days, so he lies to his good friend Bob and says that Patti is a super hot nympho with no gag reflex. Bob is elated until the date, at which time he discovers that Patti is not as advertised. Bob has standards and will not lay pipe in Patti's retarded twat, but he is a good friend and knows that Joe has not seen pussy for 972 days so he does what any good friend would do... Bob calls in his doppelbänger - who takes one for the team - allowing his good friend Joe to FINALLY see a patch of snatch, Cindy is overjoyed that her horny, helmeted cousin finally got some trouser snake, and everyone goes home happy!
Tommy: I heard you banged out Yeasty Yolanda at the party last night!
Bob: Ohhh HELL NO! I had to call in my doppelbänger to do the dirty deed.
