I saw a kid in a wheelchair and I screamed, "EXTREME PARKOUR!!!!!!!!!!!!"
Imagine if the kid in a wheelchair was in Fast and Furious. His wheelchair is the only one that keeps him going.
Extreme Wheelchair Parkour
Explanation

Listen up, buttercup. This joke is funny because it takes something sad (a kid in a wheelchair) and turns it into something rad (extreme parkour). It's funny 'cause it's unexpected. And the Fast and Furious bit? That's just icing on the cake, making fun of how over-the-top those movies are. I bet you think they're documentaries.
