Never smile at a crocodile   No, you can't get friendly with a crocodile   Don't be taken in by his welcome grin   He's imagining how well you'd fit within his skin   Never smile at a crocodile   Never dip your hat and stop to talk awhile   Never run, walk away, say good-night, not good-day   Clear the aisle but never smile at Mister Crocodile   You may very well be well bred   Lots ot etiquette in your head   But there's always some special case, time or place   To forget etiquette   For instance:   Never smile at a crocodile   No, you can't get friendly with a crocodile   Don't be taken in by his welcome grin   He's imagining how well you'd fit within his skin   Never smile at a crocodile   Never dip your hat and stop to talk awhile   Never run, walk away, say good-night, not good-day   Clear the aisle but never smile at Mister Crocodile
