A phenomenon known as "old man strength" was on full display Monday evening in southwest Springfield.

Cellphone videos showing a fistfight between two men near Kansas Expressway and Republic Road have been spreading on social media.

The videos began with two men grappling in the southbound lanes of Kansas Expressway. After the men move into the northbound lanes of Kansas, they both raise their hands.

A man in a white shirt, who appears to be considerably older than his opponent, delivered a right-hand punch that dropped the younger man.

After that, the situation appeared to calm down.

Jeff Kaegel filmed one of the videos, which had been viewed more than 180,000 times on Facebook by Tuesday afternoon.

Kaegel said he was on his way home when he came upon the scene, and his first instinct was to take out his phone and start filming in case something crazy happened and video evidence would help police.

After the situation calmed down without any serious injuries, Kaegel decided to post the video to Facebook, where it spread quickly.

"I was a little bit surprised," Kaegel said of how the video seemed to take off.

Kaegel said he doesn't know exactly what led up to the scuffle, but he was glad to see the men did not resort to using guns to solve whatever dispute they were having.

"I’m just glad they solved it old-school with fisticuffs rather than weapons," Kaegel said.

Kaegel said the incident is also a good reminder to not underestimate a man because of his age.

Jasmine Bailey, spokeswoman for the Springfield Police Department, said officers were called out to the scene but did not write a report. She said both parties were uncooperative and didn't want to press charges, so the incident was considered "handled by officer."

Here are some of the best comments on Kaegel's Facebook post:

"Old man got hands lol."

"I don't think his parents taught him to have respect for his elders. I guess he had to learn at some point in his life. You go grandpa!!"

"Young blood learned today."
