EXPLANATION Adjectival phrases can accidentally be placed next to the wrong noun, with humorous results. In the typical error, the adjectival phrase with a high-powered rifle has been placed at the end of the sentence next to house. This creates the humorous idea that it is a house with a high-powered rifle. Of course, the phrase is meant to qualify 'man'. In the corrected model, with a high-powered rifle has been placed where it should be: a man with a high-powered rifle.
In the same way, adjectival clauses can also be inserted in the wrong place accidentally. Examine this sentence: Jennifer Hawkins was wearing a hat on her head that was made of feathers. In that sentence, the adjectival clause is that was made of feathers. Obviously that clause ought to be placed as closely as possible to 'hat', the noun that it is meant to qualify. It was the hat that was made of feathers, not her head: Jennifer Hawkins was wearing on her head a hat that was made of feathers.
