I'm a little scared...

I rarely eat ranch dressing. I prefer to make my own salad dressing, but at the moment, I'm out of a few ingredients, so when I made my dinner tonight I decided to go for the ranch. I pulled the ranch out of the fridge...oh good, just enough. I proceeded to make my salad and douse it with dressing. My salad tasted fine, but as I was putting the bottle of ranch in the trash (after I finished eating) I realized that...ummm...yeah, it expired in February 2006. I'm not exactly sure what eating salad dressing that expired a year ago will do to me. I feel fine...so far.
