Rob Paulsen is one of my favorite voice actors, so it's cool to be able to hear him at random intervals throughout the day. (Even on the radio.)
It started off as just a voice over, but I guess they liked him enough to give him an actual character. I was worried awhile back because I saw a commercial that only featured images of the character and another voice actor, and I was like, "Oh, great, they dumped him in favor of someone else." But then I saw a new one a few days later with Paulsen back, so I was glad to see they hadn't gotten rid of him.
