Go back to all the commercials they've had over the years and think of the most annoying characters you've ever seen in those ads.
Here's my list:
1.The Furniture City kids ("Furniture City Pacakge Pricing!")
2. The "Zoom-Zoom" kid
3. The Wood Palace kids
4. The little cheerleader in the T-Mobile commercial (her voice goes right through me)
I'm sure there are more but that's all I can think of right now.
