NEVER
Never lick a cactus
Never hug a skunk
Never munch a mattress
Never mug a monk
Never kick a canteloupe
Never wreck a rock
Never axe an antelope
Never slurp a sock
Never swim in lava
Never tickle frogs
Never poke your father
Never pickle dogs
Never nudge a garden gnome
Never bark at Miss
Never read a poem
As ridiculous as this
writing idea: what else should one never do? Your list could rhyme, or not!
