Threes-A Terza Rima

Three witches, three wishes, three cheers. A terza rima. (Non-traditional)

Threes-A Terza Rima

The cantankerous old witches in Macbeth.
Fire and brimstone and rolling eyes,
their velvet cloaks are black with death.

Still, wishes come with compromise,
loopholes from genies and wells abound,
Lamps and pennies in disguise.

A last sort of three, alone in sound.
Hip, hip, hooray, is squealed.
An echo throughout a poem's round.
