A look back at Donald Trump's most legendary insults - and how his targets responded

As the current front-runner for the Republican presidential nomination, Donald Trump attracts media scrutiny after nearly every interview he gives. 

But not so long ago, Trump's ability to make headlines was helped by his penchant for insulting and engaging in feuds with other celebrities.

Over the years, Trump has been involved in a number of high-profile beefs with politicians, movie stars, and other public figures.

Though the real-estate magnate says he generally only attacks people who go after him first, he's shown few qualms about going for the jugular, hurling amusing and frequently offensive insults at whoever stands in his path. It's continued during his 2016 campaign, as he has lashed out at rivals, (former) business partners, and the media.

Here are some of Trump's more notable insults over the years, and the targets who dished it to him.
