An 8-year-old went from cute to straight-up savage on the Pat McAfee Show ... praising the crew for being the ultimate inspiration to a young sports fan -- and then dropping an F-bomb toward one of the co-hosts!!
The youngster called in on the popular Sirius XM show on Wednesday -- saying his name is Owen, he's 8 and 1/2 years old, and he's a massive fan of the show.
"I wanna talk about how inspiring this show is," Owen said with a soft-spoken voice. "How you're inspiring this whole entire world with how you're talking about sports and how you're talking about your life experiences."
