If he's legit, and not doing shtick, I'd say we could consider reopening the hall of shame.
Not that I condone the shenanigans of this guy, but sometimes I think the show needs new enemies to thrive. A part of me enjoys when idiots like this get on the line. Witnessing Tom wrangle dopes is the best part of the show.
It does suck when it gets out of control and the lines are tied up with nothing but crank callers and misanthropes. But it also gets monotonous when there's a string of fawning conflict-free calls. In moderation, bad callers are the spice of the show.
Not sure this Ross character has what it takes though. As far as spices go, he's no saffron.
