Or there's this:

BREAKING WIND SUDDENLY
by Les Barker, from Irritable Bow-wow Syndrome.

Breaking wind suddenly, suddenly, suddenly
Tends to exclude one from society.
Breaking wind suddenly, suddenly, suddenly,
I blamed the dog but they knew it was me.
A friend said to me there were jobs in the offing,
So I hurried to town as an interviewee.
I was almost employed when my hopes were destroyed
By a thund'rous eruption. They knew it was me.

Breaking wind suddenly, suddenly, suddenly
Somehow I feel did not help my cause.
Breaking wind suddenly, suddenly, suddenly,
I spelled out 'fart' in impeccable Morse.
I knew they were pleased with answers I'd given,
And all were impressed by my honours degree,
Then my hopes went under; I said it was thunder
But that was a blunder, they knew it was me.

Breaking wind suddenly, suddenly, suddenly;
Rippling the surface of their cups of tea.
Breaking wind suddenly, suddenly, suddenly
I knew I'd not be their new employee.
And later that evening, my old trouser coughing
Gave warning to ships on the deep rolling sea;
A great clap of thunder boomed all down the Humber;
I blame the dog, but they know it was me.
