Las Vegas weatherman for Fox 5 News Ted Pretty had a close encounter of the sassy kind while out reporting on fireworks and it's become the internet's new favourite thing.

Pretty was visiting a fireworks on sale ahead of the fourth of July when he crossed paths with a kid who had no time for his questions and responded with the sickest burn of Pretty's career.

But before you get worked up or start shouting 'Fake news!' at your screen, this was a scripted bit between Pretty and his actual son Jack who is apparently a regular feature in Pretty's reports.
