When a fan called to question the findings in the NFL's Deflategate report, Mike Francesa blew a gasket Tuesday.
Francesa, whose WFAN radio show in New York is simulcast nationally on Fox Sports 1, jumps in quickly when he realizes where the caller wants to take the conversation.
"Stop! Stop now!" Francesa says. "You're a fan who's a fool."
The call ends with Francesa telling the caller identified as Steve from Maine, "Are you nuts? Go tell someone else!"
