It's a joke, from little bunny foofoo

Should be " Hare today, goon tomorrow".
Quoted from a children's song, Little bunny Foofoo.

Little bunny foofoo I don't want see you,
hopping through the forest, scooping up the field mice,
bopping them on the head.
Here comes the good fairy,
"I'll give you three chances, if you don't behave, I'll turn you into a goon,
so hare today, goon tomorrow"
And the next day,
the next next day...
