Cris Carter To Britt McHenry -- You're On TV ... You Gotta Treat People Right

Cris Carter has a message for embattled co-worker Britt McHenry ... with great celebrity comes great responsibility ... telling TMZ Sports McHenry has a lot to learn about being in the spotlight.

Carter was out in D.C. when we asked the ESPN football analyst about McHenry's tow truck tirade and if he thought his fellow four letter personality was getting a raw deal from the public.

Check out the clip -- Carter dishes out the wisdom like a TV Yoda ... telling our camera guy if Britt is gonna live her life on camera, she needs to know how to treat people.

Bonus -- The NFL Hall of Famer makes a pretty sick one handed catch from our camera guy.
