That's the AFLAC commercials, Taciturn (voiced by Mr. Obnoxious Voice, Gilbert Gottfreid - but he's perfect for it!)
My personal favorite that's long-gone was one for Little Caesar's, which I have forever saved on my videotape of the Alabama-Miami national championship Sugar Bowl game.
In one of their "this is crazy" commercials, a wedding planner (an obvious flamer, which makes it even more over the top) is planning a dog wedding.
"Some people call it dog weddings, but we prefer Canine Nuptials!!!"
Follow this up with dogs of various breeds in tuxes and bridal/bridesmaids outfits, and chaos ensues.
