There's a guy who works the drive-thru at a McDonald's in San Diego who must LOVE his job.  His voice is ridiculous, and he says "excellent choice" after you order stuff. But here's the best part:  Apparently if you ask for "special sauce", he tells you the different sauces in the form of a RAP.  Someone posted a video of it on YouTube.

(--Search for "McDonald's special sauce song."  The rap starts at :31.)
