If you're living on beans the consequence means

Methane

And likewise no doubt are boiled brussel sprouts

For Methane

 

You'll soon lose your chums with what comes from your bum

Methane

So, quick! Blame the dog; then it's off to the bog

Methane

 

Know well, that smell from Hell's

Methane

 

To avoid rotten eggs open your legs

Methane

Then use a taper to ignite your vapour

Of Methane

 

Make sure it's a fart, not wet when you part

With Methane

You'll not want to dump be sure it's a trump

Of Methane

 

Know well, that smell from Hell's

Methane

 

It's chemical score it is CH4

That's Methane

But similarly used and sometimes confused

With Ethane

 

Know well, that smell from Hell's

Methane
