Have you ever sniggered so much
that a snot bubble came out

Have you creased  up
and then sprayed out all your drink

Have you chuckled  out a fart 
Maybe giggled out a wee

Or shoulder jiggled silently
until your face turned pink.

Can you say with pride
that your laughter button works?  

Do you care
 if the last laugh is on you?

Coz beware that if your senses 
tell your brain to make you laugh

Your brain might tell
another body part to join in too!
