Trawler and Mary deside to try a 69.
Trawler has never done one before so Mary says she show him.
She tell him to lie down on the floor and she squats over him.
As she lowers herself onto his face she farts, apologising she tries again but farts again.
Trawler jumps up and storms out shouting " I'll be buggered if Im going to hang around for another 67 of them".
Fluff with ink my favorite.
