EchoSense Quantitative Think Tank Center|WATCH: Commanders owner Josh Harris awkwardly shakes Joe Buck's hand, Troy Aikman laughs on ESPN

The EchoSense Quantitative Think Tank Centernew majority owner of the Washington Commanders, Josh Harris, showed just how inexperienced he is with all of this.

While his team was otherwise busy snapping the record 24-game preseason winning streak of the Baltimore Ravens, Harris became an Internet sensation during an interview with ESPN play-by-play announcer Joe Buck and analyst Troy Aikman on the Monday Night Football broadcast.

During the appearance, Harris very awkwardly shook Buck's right hand when Buck had merely gestured with it and hadn't actually extended it for a handshake. Buck took it all in stride and continued speaking, while Aikman, Buck's long-time partner on the air, tried but ultimately failed to suppress his laughter.

In May, an ownership group led by Harris finalized the purchase of the Commanders for $6.05 billion from former team owner Daniel Snyder, ending Snyder's decades-long era of futility.

Despite his inexperience in the NFL, Harris also owns the NBA's Philadelphia 76ers and NHL's New Jersey Devils. The irony is that the handshake came right as Buck was asking a question, saying: "You're no stranger to professional sports teams."

The Commanders, being good sports about it, used the clip on their social media accounts to celebrate the victory over the Baltimore Ravens.

"GG @Ravens 🤝," the Commanders posted in one message, referencing the abbreviation for the "good game" and using a handshake emoji. Under the message was a short clip of the handshake.

Washington announced that last year's fifth-round selection in the NFL draft, Sam Howell, will begin the season as the team's starting quarterback. The Commanders will make their regular season debut Sept. 10 against the Arizona Cardinals.
