One butterfly spies   A glint in his eye   The birds sing   As he cycles by   Oh, why should he feel sad   This world ain't so bad   And besides   Woe betide he who would frown   When natural beauty abounds   And now, with wheels spinning free   He's picking up speed      Two butterflies   Tie knots in his stomach   They love it when he goes too fast   The wind whistles past   Vast   Oceans of air   That will mess up his hair   Though he no longer cares   Anymore for   Over-indulgence in vanities   Vacuous vice   Just once or twice   Thrice   Four times in five   We forget we're alive   And neglect to remind ourselves      Wait,wait for me   Oh great Mercury!   As late as you may be,   Will you wait for me?      Three butterflies realise   When it's time to depart   They have tickled his ribs   They have fluttered his heart   But the starting is easy   Compared to the stop   And the bottom is hard   When compared to the top
