Don't ever climb cliffs with a dope
Or a novice outside of their scope.
It's you they'll betray
When they botch the belay,
And you'll seethe at the end of your rope.

The stars o'er Dakota were spangling
When Tex tried some tricky night-wrangling.
But the steers caught a whiff,
Knocked him over the cliff,
And he ended up upside-down, dangling.

A grammar professor was angling
To do some non-conjugal tangling.
But the girl got past tense
At his genitive offense,
And he left with his participle dangling.

Based on the suggestion: “climbing/dangling on a rope”

The last one departs quite a bit from the original suggestion, but the phrase "dangling particle" was too suggestive to pass up.
