Steven Tyler drops f-bomb on 'Today' during weather forecast

According to Al Roker's weather forecast Friday (Nov. 2) morning, the Pacific Northwest should expect rain and "Today" viewers should expect to hear Steven Tyler say "f***" on national television.

The Aerosmith frontman and his bandmates joked with Matt Lauer that they normally don't do morning shows, and as Roker says following the unexpected f-bomb, "That's why they haven't done mornings."  

The band was on the show to promote its new album, "Music From Another Dimension," by performing live at Rockefeller Plaza.

While warming up the crowd (and apparently unaware he could be heard on the air) during Roker's weather forecast, Tyler says, "Hey, thanks for coming out you crazy f***s."

Roker responds, "What did he just say?"

Oh, you heard him right, Al.
