Some fools are summer fools
other fools are sommerfugls
fugls are birds, yes, summer birds
but summer birds are butterflies
I don’t think butterflies can hum
but hummingbirds can hum and fly
flies and birds and soon it’s fall
the summer fools fool us all

For the Ragtag Daily Prompt: hum.

Sommerfugl is Danish and is pronounced summer fool. The literal translation is summer bird, but it means butterfly.
