This kid is gas. 

After catching the passenger behind him doing something gross with her feet, a hilarious little boy was having none of it.

Four-year old Rodney Small was waiting to depart on a flight from Houston to Florida with his father Darryl, when he noticed a woman had placed her bare “stinky feet” on his armrest, The Sun reported.

The 28-year-old dad was filming his son’s reaction on his first flight, to capture the funny situation.

In the video, the young boy looks at the camera and says, “There are stinky feet behind me.”

He then looks at the foot before peering around at the culprit, saying in shock: “It’s a lady!”

Darryl bursts out laughing at his son’s reaction, covering his eyes as he cracks up.

 

The boy then looks back and says, “Someone has their feet behind me,” before telling the woman off.

Darryl later explained the woman apologised and moved her bare feet.

“As a child he knew that putting your foot in someone else’s space was not kind at all,” he told Unilad.

“Sometimes adults hold back with confronting others to keep the peace, but as a child he voiced his concerns, and his facial expressions and reaction made it hilarious.”

The video, which was posted to Facebook, has gone viral with other social media users siding with the boy.

“Absolutely NO NEED to apologise,” A facebook user commented. “People who do that are rude. I’m glad your son said something. Nothing better than the upfront honesty of a child.”

Someone else agreed: “No need to apologise to her! She’s grown and should know better! Love this lil man! So cute and honest!!!”

Another said: “He needs to be the Airlines Ambassador for Airline Etiquette.”
