Yesterday on 'Today,' weatherman Al Roker made an on-air flub when he referred to anchor Savannah Guthrie by using the wrong name. Oops! You're slipping, Al.

Apparently, Roker jokingly calls Guthrie a variety of names backstage, everything from "Sesquahanna" to "Shawanda." (Oh, that Al. Such a jokester.) But this time, it was for real when Roker called her "Samantha" on live TV and wasn't aware of it.

Watch the gaffe below.
