'Today' host disrupts live telecast with 'Glee' ringtone

It was bad enough last week when the fire alarm sounded in the middle of "NBC Nightly News with Brian Williams." Now these kind of on-air interruptions are becoming something of a habit for NBC News.

But it may have been worse Tuesday on "Today." Not just because co-host Savannah Guthrie left her iPhone on during a live telecast, prompting her to turn several shades of crimson as her colleagues scrambled to make light of the disruption and take the device away from her. What made it worse was the music coming from the phone: a selection from "Glee," the hit series from that other TV network, Fox.

Next time, Savannah, just make "The Office" theme your ringtone.
