Oh! This is a weird, specific one, but I HATE on the Today show, when they tease a story and then say, "But first, this is Today on NBC."
But first? Huh? It's just weird. "But first, these messages," maybe. "But first, a word from our sponsor." But not "But first, this is Today..."
Also, I never got at the end of 20/20, when Barbara Walters would say, "And remember, we're in touch, so you be in touch." I could never figure out what she meant by that.
