Have you heard the one about the farting velodrome?

I get enough of that in this office. Don't need no velodrome that's for sure. 😖 

See, if it sounded like a motorbike I could understand it. a boil up the bum will cause that.

Because, abscess makes the fart go Honda.

Sounds like the echelon effect.  I can't find an online description of it, but it is where sounds reflect off a corrugated or similar surface at different delays resulting in a smearing out.  You can hear it if you stand next to a long fence with vertical overlapping planks and clap your hands.

Cougar, I think you need to go and sit in the corner and think about what you've done.

Watching Sean Lock on fart humour the other night - "Better out than in," said Tinkerbell as she floated by, leaving a sprinkle of fairy dust and the faint whiff of shit" 😆
