It's Catchy

 

For what we have there is no cure

Stand way back – don’t breathe,

 

The is no hope and that’s for sure

behind the rope - please,

 

It spreads by way of grammar

Most things get mispronounced

You’ll even get a stammer

when on you this does pounce,

 

Vocabulary suffers

speech will run a muck

no literary buffers

I’m afraid you’ll

just be stuck.

 

You’ll need to pay attention

take notes just to be sure

for the things I fail to mention

may cause you all to slur.
