The colon and the semi-colon
Went walking on the beach
Said the semi to the colon:
“You really are a peach;
I love the way you introduce
Thought and word and deed.”

Smiled the blushing colon:
“Semi, you’re the one we need;
Connecting sentences is far beyond my reach.”

And so the pair went walking on,
Contented, down the shore;
Each believed it was the other
Who bore the greater chore.
