Never smile at a crocodile
No you can't be friends with Mr Crocodile
Don't be taken in
By his toothsome grin
He's imagining how well you'd fit within his skin

Never smile at a crocodile
Never tip your hat and stop to talk a while
Never run, walk away
Say goodbye and not good day
Clear the aisle and never smile at Mr Crocodile

You may be very well bred
Lots of etiquette in your head
But there's always some special case
Time or place
To forget
Etiquette

Remember!

Never smile...
