If your system can handle it, watch a movie while you grind. Do this by going into your login screen, click "Options," and choose windowed mode. Squish your screen down and have the movie (or TV series) running below it on your screen. How big do the mobs have to be, honestly, for you to kill and loot?
If your system can't handle video+WoW, try some radio programs or audio books. Your local library is almost sure to have popular books on CD that you can check out (from Stephen King to Twilight) and my husband loves to listen to This American Life, which streams shows for free from their website. I personally have all of the Lake Wobegon discs on my Amazon wishlist because Garrison Keillor cracks me up.
The only drawback is you can't watch anything subtitled.
