In no particular order. Inspired by @gwcoffey, thanks for saying you like mine!
  1. The Swedish Chef
  2. Tom Jones
  3. Dustin Hoffman as Dorothy in Tootsie
    I love the little lilt and southern accent in her voice.
  4. Bill Murray
    As Bill Murray
  5. Maya Angelou
  6. Sophia Loren, Salma Hayek, Penelope Cruz
    Really any woman with a Latin accent does it for me.
