Richard Sherman Goes Undercover As Lyft Driver ... Hilariously Clowns Himself

Check yourself the next time your Lyft driver tries to bait you into talking smack about Richard Sherman -- 'cause the guy might actually be Richard Sherman!

The Seattle Seahawks superstar went undercover as a Lyft driver -- IN SEATTLE -- to see how unsuspecting commuters felt about him. The result is pretty damn hilarious.

Sherman was dropping subtle hints about his true identity along the way ... including this gem:

"I just came back from Hawaii actually with some of my friends. I try to make sure I go every year. There's like 50 of us. We even see some guys we really don't like so much from work but that's part of the job."
