The pipe bomb sent to CNN’s Midtown headquarters Wednesday had an ISIS parody flag reading “Get ‘Er Done” on it, a high-ranking police source told The Post.

The mock flag appears to be one that has been lurking on the right-wing corners of the internet as a meme since 2014.

It replaces Arabic characters with the suggestive silhouettes of three women and the words “Get ‘Er Done” — which is the catchphrase of stand-up comic Larry the Cable Guy.

The image was originally created by the right-wing parody site World News Bureau for an article titled “ISIS Vows Retribution For Counterfeit Flags,” according to NBC News.

Based on a picture of the bomb obtained by CNN, there appears to be the image of a face next to the mock flag. The identity of the person in that picture is still unknown.

The bomb sent to CNN, and addressed to former CIA Director John Brennan, is one of many makeshift bombs sent to a number of prominent Democrats — including former President Barack Obama and Hillary Clinton.
